Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).
Idea for using the TAP system from Tom, though all of the code is mine.

Provide test coverage in pg_dump for default behaviors with compression
By default, the contents generated by the custom and directory dump
formats are compressed. However, with the existing test facility, the
restore program will succeed regardless of whether the dumped output was
compressed or not without checking if anything has been compressed.
This commit implements a portable way to check the contents of the
custom and directory dump formats:
- glob_patterns, that can be defined for each test as an array of
glob()-compilable strings, tracking the contents that should or should
not be compressed. While this is useful to make sure that the table
data is compressed, this also checks that blobs.toc and toc.dat are
never compressed.
- command_like, to execute a command on a dump and check its generated
output. This is used here in correlation with pg_restore -l to check if
the dumps have been compressed or not, depending on if the build
supports gzip, or not.
This hole in the tests has come up when working on 5e73a60, where
compression has to be applied by default, if available, for both dump
formats.
The idea of glob_patterns comes from me, and Georgios has come up with
the design for command_like.

pg_upgrade: Fix large object COMMENTS, SECURITY LABELS
When performing a pg_upgrade, we copy the files behind pg_largeobject
and pg_largeobject_metadata, allowing us to avoid having to dump out and
reload the actual data for large objects and their ACLs.
Unfortunately, that isn't all of the information which can be associated
with large objects. Currently, we also support COMMENTs and SECURITY
LABELs with large objects and these were being silently dropped during a
pg_upgrade as pg_dump would skip everything having to do with a large
object and pg_upgrade only copied the tables mentioned to the new
cluster.
As the file copies happen after the catalog dump and reload, we can't
simply include the COMMENTs and SECURITY LABELs in pg_dump's binary-mode
output but we also have to include the actual large object definition as
well. With the definition, comments, and security labels in the pg_dump
output and the file copies performed by pg_upgrade, all of the data and
metadata associated with large objects is able to be successfully pulled
forward across a pg_upgrade.
In 9.6 and master, we can simply adjust the dump bitmask to indicate
which components we don't want. In 9.5 and earlier, we have to put
explciit checks in in dumpBlob() and dumpBlobs() to not include the ACL
or the data when in binary-upgrade mode.
Adjustments made to the privileges regression test to allow another test
(large_object.sql) to be added which explicitly leaves a large object
with a comment in place to provide coverage of that case with
pg_upgrade.
Back-patch to all supported branches.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).
Idea for using the TAP system from Tom, though all of the code is mine.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

# Do not use --no-sync to give test coverage for data sync.
Provide test coverage in pg_dump for default behaviors with compression
By default, the contents generated by the custom and directory dump
formats are compressed. However, with the existing test facility, the
restore program will succeed regardless of whether the dumped output was
compressed or not without checking if anything has been compressed.
This commit implements a portable way to check the contents of the
custom and directory dump formats:
- glob_patterns, that can be defined for each test as an array of
glob()-compilable strings, tracking the contents that should or should
not be compressed. While this is useful to make sure that the table
data is compressed, this also checks that blobs.toc and toc.dat are
never compressed.
- command_like, to execute a command on a dump and check its generated
output. This is used here in correlation with pg_restore -l to check if
the dumps have been compressed or not, depending on if the build
supports gzip, or not.
This hole in the tests has come up when working on 5e73a60, where
compression has to be applied by default, if available, for both dump
formats.
The idea of glob_patterns comes from me, and Georgios has come up with
the design for command_like.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels

There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).
Idea for using the TAP system from Tom, though all of the code is mine.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries

# Definition of the tests to run.
#
# Each test is defined using the log message that will be used.
#
# A regexp should be defined for each test which provides the
# basis for the test. That regexp will be run against the output
# file of each of the runs which the test is to be run against
# and the success of the result will depend on if the regexp
# result matches the expected 'like' or 'unlike' case.
#
Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

# The runs listed as 'like' will be checked if they match the

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).
Idea for using the TAP system from Tom, though all of the code is mine.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)

only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).
Idea for using the TAP system from Tom, though all of the code is mine.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).
Idea for using the TAP system from Tom, though all of the code is mine.

unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a

unless it's listed in 'unlike' in which case it's an 'unlike'. If it

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).
Idea for using the TAP system from Tom, though all of the code is mine.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when

to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path

was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options

- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config

Last, but not least, this approximately halves the number of tests run

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Make pg_dump emit ATTACH PARTITION instead of PARTITION OF (reprise)
Using PARTITION OF can result in column ordering being changed from the
database being dumped, if the partition uses a column layout different
from the parent's. It's not pg_dump's job to editorialize on table
definitions, so this is not acceptable; back-patch all the way back to
pg10, where partitioned tables where introduced.
This change also ensures that partitions end up in the correct
tablespace, if different from the parent's; this is an oversight in
ca4103025dfe (in pg12 only). Partitioned indexes (in pg11) don't have
this problem, because they're already created as independent indexes and
attached to their parents afterwards.
This change also has the advantage that the partition is restorable from
the dump (as a standalone table) even if its parent table isn't
restored.
The original commits (3b23552ad8bb in branch master) failed to cover
subsidiary column elements correctly, such as NOT NULL constraint and
CHECK constraints, as reported by Rushabh Lathia (initially as a failure
to restore serial columns). They were reverted. This recapitulation
commit fixes those problems.
Add some pg_dump tests to verify these things more exhaustively,
including constraints with legacy-inheritance tables, which were not
tested originally. In branches 10 and 11, add a local constraint to the
pg_dump test partition that was added by commit 2d7eeb1b1492 to master.

This change also has the advantage that the partition is restorable from
the dump (as a standalone table) even if its parent table isn't
restored.
The original commits (3b23552ad8bb in branch master) failed to cover
subsidiary column elements correctly, such as NOT NULL constraint and
CHECK constraints, as reported by Rushabh Lathia (initially as a failure
to restore serial columns). They were reverted. This recapitulation
commit fixes those problems.
Add some pg_dump tests to verify these things more exhaustively,
including constraints with legacy-inheritance tables, which were not
tested originally. In branches 10 and 11, add a local constraint to the
pg_dump test partition that was added by commit 2d7eeb1b1492 to master.

Make pg_dump emit ATTACH PARTITION instead of PARTITION OF (reprise)
Using PARTITION OF can result in column ordering being changed from the
database being dumped, if the partition uses a column layout different
from the parent's. It's not pg_dump's job to editorialize on table
definitions, so this is not acceptable; back-patch all the way back to
pg10, where partitioned tables where introduced.
This change also ensures that partitions end up in the correct
tablespace, if different from the parent's; this is an oversight in
ca4103025dfe (in pg12 only). Partitioned indexes (in pg11) don't have
this problem, because they're already created as independent indexes and
attached to their parents afterwards.

the dump (as a standalone table) even if its parent table isn't

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

'ALTER FOREIGN TABLE foreign_table OWNER TO' = > {
Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the

- Use command_fails_like instead of command_exit_is
- Operator classes, operator families

- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

pg_dump: Fix gzip compression of empty data
The pg_dump Compressor API has three basic callbacks - Allocate, Write
and End. The gzip implementation (since e9960732a) wrongly assumed the
Write function would always be called, and deferred the initialization
of the internal compression system until the first such call. But when
there's no data to compress (e.g. for empty LO), this would result in
not finalizing the compression state (because it was not actually
initialized), producing invalid dump.
Fixed by initializing the internal compression system in the Allocate
call, whenever the caller provides the Write. For decompression the
state is not needed, so we leave the private_data member unpopulated.
Introduces a pg_dump TAP test compressing an empty large object.
This also rearranges the functions to their original order, to make
diffs against older code simpler to understand. Finally, replace an
unreachable pg_fatal() with a simple assert check.

Move handling of database properties from pg_dumpall into pg_dump.
This patch rearranges the division of labor between pg_dump and pg_dumpall
so that pg_dump itself handles all properties attached to a single
database. Notably, a database's ACL (GRANT/REVOKE status) and local GUC
settings established by ALTER DATABASE SET and ALTER ROLE IN DATABASE SET
can be dumped and restored by pg_dump. This is a long-requested
improvement.
"pg_dumpall -g" will now produce only role- and tablespace-related output,
nothing about individual databases. The total output of a regular
pg_dumpall run remains the same.
pg_dump (or pg_restore) will restore database-level properties only when
creating the target database with --create. This applies not only to
ACLs and GUCs but to the other database properties it already handled,
that is database comments and security labels. This is more consistent
and useful, but does represent an incompatibility in the behavior seen
without --create.
(This change makes the proposed patch to have pg_dump use "COMMENT ON
DATABASE CURRENT_DATABASE" unnecessary, since there is no case where
the command is issued that we won't know the true name of the database.
We might still want that patch as a feature in its own right, but pg_dump
no longer needs it.)
pg_dumpall with --clean will now drop and recreate the "postgres" and
"template1" databases in the target cluster, allowing their locale and
encoding settings to be changed if necessary, and providing a cleaner
way to set nondefault tablespaces for them than we had before. This
means that such a script must now always be started in the "postgres"
database; the order of drops and reconnects will not work otherwise.
Without --clean, the script will not adjust any database-level properties
of those two databases (including their comments, ACLs, and security
labels, which it formerly would try to set).
Another minor incompatibility is that the CREATE DATABASE commands in a
pg_dumpall script will now always specify locale and encoding settings.
Formerly those would be omitted if they matched the cluster's default.
While that behavior had some usefulness in some migration scenarios,
it also posed a significant hazard of unwanted locale/encoding changes.
To migrate to another locale/encoding, it's now necessary to use pg_dump
without --create to restore into a database with the desired settings.
Commit 4bd371f6f's hack to emit "SET default_transaction_read_only = off"
is gone: we now dodge that problem by the expedient of not issuing ALTER
DATABASE SET commands until after reconnecting to the target database.
Therefore, such settings won't apply during the restore session.
In passing, improve some shaky grammar in the docs, and add a note pointing
out that pg_dumpall's output can't be expected to load without any errors.
(Someday we might want to fix that, but this is not that patch.)

Vaishnavi Prabakaran, and Robert Haas; further hacking by me.

Improve pg_dump's handling of "special" built-in objects.
We had some pretty ad-hoc handling of the public schema and the plpgsql
extension, which are both presumed to exist in template0 but might be
modified or deleted in the database being dumped.
Up to now, by default pg_dump would emit a CREATE EXTENSION IF NOT EXISTS
command as well as a COMMENT command for plpgsql. The usefulness of the
former is questionable, and the latter caused annoying errors in
non-superuser dump/restore scenarios. Let's instead install a rule that
built-in extensions (identified by having low-numbered OIDs) are not to be
dumped. We were doing it that way already in binary-upgrade mode, so this
just makes regular mode behave the same. It remains true that if someone
has installed a non-default ACL on the plpgsql language, that will get
dumped thanks to the pg_init_privs mechanism. This is more consistent with
the handling of built-in objects of other kinds.
Also, change the very ad-hoc mechanism that was used to avoid dumping
creation and comment commands for the public schema. Instead of hardwiring
a test in _printTocEntry(), make use of the DUMP_COMPONENT_ infrastructure
to mark that schema up-front about what we want to do with it. This has
the visible effect that the public schema won't be mentioned in the output
at all, except for updating its ACL if it has a non-default ACL.
Previously, while it was normally not mentioned, --clean mode would drop
and recreate it, again causing headaches for non-superuser usage. This
change likewise makes the public schema less special and more like other
built-in objects.
If plpgsql, or the public schema, has been removed entirely in the source
DB, that situation won't be reproduced in the destination ... but that
was true before.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).
Idea for using the TAP system from Tom, though all of the code is mine.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

IS \ 'comment on enum type\';' ,
Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

IS \ 'comment on range type\';' ,
Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

# In a data-only dump, we try to actually order according to FKs,
2016-11-18 20:21:33 +01:00
# so this check is just making sure that the referring table comes after
# the referred-to table.
Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).
Idea for using the TAP system from Tom, though all of the code is mine.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

'INSERT INTO test_fourth_table' = > {
Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Canonicalize ICU locale names to language tags.
Convert to BCP47 language tags before storing in the catalog, except
during binary upgrade or when the locale comes from an existing
collation or template database.
The resulting language tags can vary slightly between ICU
versions. For instance, "@colBackwards=yes" is converted to
"und-u-kb-true" in older versions of ICU, and to the simpler (but
equivalent) "und-u-kb" in newer versions.
The process of canonicalizing to a language tag also understands more
input locale string formats than ucol_open(). For instance,
"fr_CA.UTF-8" is misinterpreted by ucol_open() and the region is
ignored; effectively treating it the same as the locale "fr" and
opening the wrong collator. Canonicalization properly interprets the
language and region, resulting in the language tag "fr-CA", which can
then be understood by ucol_open().
This commit fixes a problem in prior versions due to ucol_open()
misinterpreting locale strings as described above. For instance,
creating an ICU collation with locale "fr_CA.UTF-8" would store that
string directly in the catalog, which would later be passed to (and
misinterpreted by) ucol_open(). After this commit, the locale string
will be canonicalized to language tag "fr-CA" in the catalog, which
will be properly understood by ucol_open(). Because this fix affects
the resulting collator, we cannot change the locale string stored in
the catalog for existing databases or collations; otherwise we'd risk
corrupting indexes. Therefore, only canonicalize locales for
newly-created (not upgraded) collations/databases. For similar
reasons, do not backport.

Improve pg_dump's handling of "special" built-in objects.
We had some pretty ad-hoc handling of the public schema and the plpgsql
extension, which are both presumed to exist in template0 but might be
modified or deleted in the database being dumped.
Up to now, by default pg_dump would emit a CREATE EXTENSION IF NOT EXISTS
command as well as a COMMENT command for plpgsql. The usefulness of the
former is questionable, and the latter caused annoying errors in
non-superuser dump/restore scenarios. Let's instead install a rule that
built-in extensions (identified by having low-numbered OIDs) are not to be
dumped. We were doing it that way already in binary-upgrade mode, so this
just makes regular mode behave the same. It remains true that if someone
has installed a non-default ACL on the plpgsql language, that will get
dumped thanks to the pg_init_privs mechanism. This is more consistent with
the handling of built-in objects of other kinds.
Also, change the very ad-hoc mechanism that was used to avoid dumping
creation and comment commands for the public schema. Instead of hardwiring
a test in _printTocEntry(), make use of the DUMP_COMPONENT_ infrastructure
to mark that schema up-front about what we want to do with it. This has
the visible effect that the public schema won't be mentioned in the output
at all, except for updating its ACL if it has a non-default ACL.
Previously, while it was normally not mentioned, --clean mode would drop
and recreate it, again causing headaches for non-superuser usage. This
change likewise makes the public schema less special and more like other
built-in objects.
If plpgsql, or the public schema, has been removed entirely in the source
DB, that situation won't be reproduced in the destination ... but that
was true before.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Explicitly track whether aggregate final functions modify transition state.
Up to now, there's been hard-wired assumptions that normal aggregates'
final functions never modify their transition states, while ordered-set
aggregates' final functions always do. This has always been a bit
limiting, and in particular it's getting in the way of improving the
built-in ordered-set aggregates to allow merging of transition states.
Therefore, let's introduce catalog and CREATE AGGREGATE infrastructure
that lets the finalfn's behavior be declared explicitly.
There are now three possibilities for the finalfn behavior: it's purely
read-only, it trashes the transition state irrecoverably, or it changes
the state in such a way that no more transfn calls are possible but the
state can still be passed to other, compatible finalfns. There are no
examples of this third case today, but we'll shortly make the built-in
OSAs act like that.
This change allows user-defined aggregates to explicitly disclaim support
for use as window functions, and/or to prevent transition state merging,
if their implementations cannot handle that. While it was previously
possible to handle the window case with a run-time error check, there was
not any way to prevent transition state merging, which in retrospect is
something commit 804163bc2 should have provided for. But better late
than never.
In passing, split out pg_aggregate.c's extern function declarations into
a new header file pg_aggregate_fn.h, similarly to what we've done for
some other catalog headers, so that pg_aggregate.h itself can be safe
for frontend files to include. This lets pg_dump use the symbolic
names for relevant constants.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Multirange datatypes
Multiranges are basically sorted arrays of non-overlapping ranges with
set-theoretic operations defined over them.
Since v14, each range type automatically gets a corresponding multirange
datatype. There are both manual and automatic mechanisms for naming multirange
types. Once can specify multirange type name using multirange_type_name
attribute in CREATE TYPE. Otherwise, a multirange type name is generated
automatically. If the range type name contains "range" then we change that to
"multirange". Otherwise, we add "_multirange" to the end.
Implementation of multiranges comes with a space-efficient internal
representation format, which evades extra paddings and duplicated storage of
oids. Altogether this format allows fetching a particular range by its index
in O(n).
Statistic gathering and selectivity estimation are implemented for multiranges.
For this purpose, stored multirange is approximated as union range without gaps.
This field will likely need improvements in the future.
Catversion is bumped.

Add TAP tests for pg_dump

the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the

defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c

'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding

Multirange datatypes
Multiranges are basically sorted arrays of non-overlapping ranges with
set-theoretic operations defined over them.
Since v14, each range type automatically gets a corresponding multirange
datatype. There are both manual and automatic mechanisms for naming multirange
types. Once can specify multirange type name using multirange_type_name
attribute in CREATE TYPE. Otherwise, a multirange type name is generated
automatically. If the range type name contains "range" then we change that to
"multirange". Otherwise, we add "_multirange" to the end.
Implementation of multiranges comes with a space-efficient internal
representation format, which evades extra paddings and duplicated storage of
oids. Altogether this format allows fetching a particular range by its index
in O(n).
Statistic gathering and selectivity estimation are implemented for multiranges.
For this purpose, stored multirange is approximated as union range without gaps.
This field will likely need improvements in the future.
Catversion is bumped.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump

result in dump/restore misbehavior, or in privilege escalation if a

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)

- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types

defined for the test under the 'like' and 'unlike' functions, as

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Reconsider the handling of procedure OUT parameters.
Commit 2453ea142 redefined pg_proc.proargtypes to include the types of
OUT parameters, for procedures only. While that had some advantages
for implementing the SQL-spec behavior of DROP PROCEDURE, it was pretty
disastrous from a number of other perspectives. Notably, since the
primary key of pg_proc is name + proargtypes, this made it possible to
have multiple procedures with identical names + input arguments and
differing output argument types. That would make it impossible to call
any one of the procedures by writing just NULL (or "?", or any other
data-type-free notation) for the output argument(s). The change also
seems likely to cause grave confusion for client applications that
examine pg_proc and expect the traditional definition of proargtypes.
Hence, revert the definition of proargtypes to what it was, and
undo a number of complications that had been added to support that.
To support the SQL-spec behavior of DROP PROCEDURE, when there are
no argmode markers in the command's parameter list, we perform the
lookup both ways (that is, matching against both proargtypes and
proallargtypes), succeeding if we get just one unique match.
In principle this could result in ambiguous-function failures
that would not happen when using only one of the two rules.
However, overloading of procedure names is thought to be a pretty
rare usage, so this shouldn't cause many problems in practice.
Postgres-specific code such as pg_dump can defend against any
possibility of such failures by being careful to specify argmodes
for all procedure arguments.
This also fixes a few other bugs in the area of CALL statements
with named parameters, and improves the documentation a little.
catversion bump forced because the representation of procedures
with OUT arguments changes.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when

to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path

(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant

This patch changes pg_dump so that it does not change the search_path

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).

the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only

There is more which can, and should, be done here to improve the

- FDWs, servers, foreign tables

There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)

Allow publishing the tables of schema.
A new option "FOR ALL TABLES IN SCHEMA" in Create/Alter Publication allows
one or more schemas to be specified, whose tables are selected by the
publisher for sending the data to the subscriber.
The new syntax allows specifying both the tables and schemas. For example:
CREATE PUBLICATION pub1 FOR TABLE t1,t2,t3, ALL TABLES IN SCHEMA s1,s2;
OR
ALTER PUBLICATION pub1 ADD TABLE t1,t2,t3, ALL TABLES IN SCHEMA s1,s2;
A new system table "pg_publication_namespace" has been added, to maintain
the schemas that the user wants to publish through the publication.
Modified the output plugin (pgoutput) to publish the changes if the
relation is part of schema publication.
Updates pg_dump to identify and dump schema publications. Updates the \d
family of commands to display schema publications and \dRp+ variant will
now display associated schemas if any.

Last, but not least, this approximately halves the number of tests run

adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly

There is more which can, and should, be done here to improve the

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Allow specifying column lists for logical replication
This allows specifying an optional column list when adding a table to
logical replication. The column list may be specified after the table
name, enclosed in parentheses. Columns not included in this list are not
sent to the subscriber, allowing the schema on the subscriber to be a
subset of the publisher schema.
For UPDATE/DELETE publications, the column list needs to cover all
REPLICA IDENTITY columns. For INSERT publications, the column list is
arbitrary and may omit some REPLICA IDENTITY columns. Furthermore, if
the table uses REPLICA IDENTITY FULL, column list is not allowed.
The column list can contain only simple column references. Complex
expressions, function calls etc. are not allowed. This restriction could
be relaxed in the future.
During the initial table synchronization, only columns included in the
column list are copied to the subscriber. If the subscription has
several publications, containing the same table with different column
lists, columns specified in any of the lists will be copied.
This means all columns are replicated if the table has no column list
at all (which is treated as column list with all columns), or when of
the publications is defined as FOR ALL TABLES (possibly IN SCHEMA that
matches the schema of the table).
For partitioned tables, publish_via_partition_root determines whether
the column list for the root or the leaf relation will be used. If the
parameter is 'false' (the default), the list defined for the leaf
relation is used. Otherwise, the column list for the root partition
will be used.
Psql commands \dRp+ and \d <table-name> now display any column lists.

Improve pg_dump's handling of "special" built-in objects.
We had some pretty ad-hoc handling of the public schema and the plpgsql
extension, which are both presumed to exist in template0 but might be
modified or deleted in the database being dumped.
Up to now, by default pg_dump would emit a CREATE EXTENSION IF NOT EXISTS
command as well as a COMMENT command for plpgsql. The usefulness of the
former is questionable, and the latter caused annoying errors in
non-superuser dump/restore scenarios. Let's instead install a rule that
built-in extensions (identified by having low-numbered OIDs) are not to be
dumped. We were doing it that way already in binary-upgrade mode, so this
just makes regular mode behave the same. It remains true that if someone
has installed a non-default ACL on the plpgsql language, that will get
dumped thanks to the pg_init_privs mechanism. This is more consistent with
the handling of built-in objects of other kinds.
Also, change the very ad-hoc mechanism that was used to avoid dumping
creation and comment commands for the public schema. Instead of hardwiring
a test in _printTocEntry(), make use of the DUMP_COMPONENT_ infrastructure
to mark that schema up-front about what we want to do with it. This has
the visible effect that the public schema won't be mentioned in the output
at all, except for updating its ACL if it has a non-default ACL.
Previously, while it was normally not mentioned, --clean mode would drop
and recreate it, again causing headaches for non-superuser usage. This
change likewise makes the public schema less special and more like other
built-in objects.
If plpgsql, or the public schema, has been removed entirely in the source
DB, that situation won't be reproduced in the destination ... but that
was true before.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Add TAP tests for pg_dump

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints

Using PARTITION OF can result in column ordering being changed from the
database being dumped, if the partition uses a column layout different
from the parent's. It's not pg_dump's job to editorialize on table
definitions, so this is not acceptable; back-patch all the way back to
pg10, where partitioned tables where introduced.
This change also ensures that partitions end up in the correct
tablespace, if different from the parent's; this is an oversight in
ca4103025dfe (in pg12 only). Partitioned indexes (in pg11) don't have
this problem, because they're already created as independent indexes and
attached to their parents afterwards.
This change also has the advantage that the partition is restorable from
the dump (as a standalone table) even if its parent table isn't
restored.
The original commits (3b23552ad8bb in branch master) failed to cover
subsidiary column elements correctly, such as NOT NULL constraint and
CHECK constraints, as reported by Rushabh Lathia (initially as a failure

commit fixes those problems.
Add some pg_dump tests to verify these things more exhaustively,
including constraints with legacy-inheritance tables, which were not
tested originally. In branches 10 and 11, add a local constraint to the
pg_dump test partition that was added by commit 2d7eeb1b1492 to master.

These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in

Make pg_dump emit ATTACH PARTITION instead of PARTITION OF (reprise)
Using PARTITION OF can result in column ordering being changed from the
database being dumped, if the partition uses a column layout different
from the parent's. It's not pg_dump's job to editorialize on table
definitions, so this is not acceptable; back-patch all the way back to
pg10, where partitioned tables where introduced.
This change also ensures that partitions end up in the correct
tablespace, if different from the parent's; this is an oversight in
ca4103025dfe (in pg12 only). Partitioned indexes (in pg11) don't have
this problem, because they're already created as independent indexes and
attached to their parents afterwards.
This change also has the advantage that the partition is restorable from
the dump (as a standalone table) even if its parent table isn't
restored.
The original commits (3b23552ad8bb in branch master) failed to cover
subsidiary column elements correctly, such as NOT NULL constraint and
CHECK constraints, as reported by Rushabh Lathia (initially as a failure
to restore serial columns). They were reverted. This recapitulation
commit fixes those problems.
Add some pg_dump tests to verify these things more exhaustively,
including constraints with legacy-inheritance tables, which were not
tested originally. In branches 10 and 11, add a local constraint to the
pg_dump test partition that was added by commit 2d7eeb1b1492 to master.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will

Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding

Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Allow specifying column lists for logical replication
This allows specifying an optional column list when adding a table to
logical replication. The column list may be specified after the table
name, enclosed in parentheses. Columns not included in this list are not
sent to the subscriber, allowing the schema on the subscriber to be a
subset of the publisher schema.
For UPDATE/DELETE publications, the column list needs to cover all
REPLICA IDENTITY columns. For INSERT publications, the column list is
arbitrary and may omit some REPLICA IDENTITY columns. Furthermore, if
the table uses REPLICA IDENTITY FULL, column list is not allowed.
The column list can contain only simple column references. Complex
expressions, function calls etc. are not allowed. This restriction could
be relaxed in the future.
During the initial table synchronization, only columns included in the
column list are copied to the subscriber. If the subscription has
several publications, containing the same table with different column
lists, columns specified in any of the lists will be copied.
This means all columns are replicated if the table has no column list
at all (which is treated as column list with all columns), or when of
the publications is defined as FOR ALL TABLES (possibly IN SCHEMA that
matches the schema of the table).
For partitioned tables, publish_via_partition_root determines whether
the column list for the root or the leaf relation will be used. If the
parameter is 'false' (the default), the list defined for the leaf
relation is used. Otherwise, the column list for the root partition
will be used.
Psql commands \dRp+ and \d <table-name> now display any column lists.

column list are copied to the subscriber. If the subscription has
several publications, containing the same table with different column
lists, columns specified in any of the lists will be copied.
This means all columns are replicated if the table has no column list
at all (which is treated as column list with all columns), or when of
the publications is defined as FOR ALL TABLES (possibly IN SCHEMA that
matches the schema of the table).
For partitioned tables, publish_via_partition_root determines whether
the column list for the root or the leaf relation will be used. If the
parameter is 'false' (the default), the list defined for the leaf
relation is used. Otherwise, the column list for the root partition
will be used.
Psql commands \dRp+ and \d <table-name> now display any column lists.

Allow specifying column lists for logical replication
This allows specifying an optional column list when adding a table to
logical replication. The column list may be specified after the table
name, enclosed in parentheses. Columns not included in this list are not
sent to the subscriber, allowing the schema on the subscriber to be a
subset of the publisher schema.
For UPDATE/DELETE publications, the column list needs to cover all
REPLICA IDENTITY columns. For INSERT publications, the column list is
arbitrary and may omit some REPLICA IDENTITY columns. Furthermore, if
the table uses REPLICA IDENTITY FULL, column list is not allowed.
The column list can contain only simple column references. Complex
expressions, function calls etc. are not allowed. This restriction could
be relaxed in the future.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Include ALTER INDEX SET STATISTICS in pg_dump
The new grammar pattern of ALTER INDEX SET STATISTICS able to use column
numbers on top of the existing column names introduced by commit 5b6d13e
forgot to add support for the feature in pg_dump, so defining statistics
on index columns was missing from the dumps, potentially causing silent
planning problems with a subsequent restore.
pg_dump ought to not use column names in what it generates as these are
automatically generated by the server and could conflict with real
relation attributes with matching patterns. "expr" and "exprN", N
incremented automatically after the creation of the first one, are used
as default attribute names for index expressions, and that could easily
match what is defined in other relations, causing the dumps to fail if
some of those attributes are renamed at some point. So to avoid any
problems, the new grammar with column numbers gets used.

Make pg_dump emit ATTACH PARTITION instead of PARTITION OF (reprise)
Using PARTITION OF can result in column ordering being changed from the
database being dumped, if the partition uses a column layout different
from the parent's. It's not pg_dump's job to editorialize on table
definitions, so this is not acceptable; back-patch all the way back to
pg10, where partitioned tables where introduced.
This change also ensures that partitions end up in the correct
tablespace, if different from the parent's; this is an oversight in
ca4103025dfe (in pg12 only). Partitioned indexes (in pg11) don't have
this problem, because they're already created as independent indexes and
attached to their parents afterwards.
This change also has the advantage that the partition is restorable from
the dump (as a standalone table) even if its parent table isn't
restored.
The original commits (3b23552ad8bb in branch master) failed to cover
subsidiary column elements correctly, such as NOT NULL constraint and
CHECK constraints, as reported by Rushabh Lathia (initially as a failure
to restore serial columns). They were reverted. This recapitulation
commit fixes those problems.
Add some pg_dump tests to verify these things more exhaustively,
including constraints with legacy-inheritance tables, which were not
tested originally. In branches 10 and 11, add a local constraint to the
pg_dump test partition that was added by commit 2d7eeb1b1492 to master.

regression test, reducing verbosity on a cascaded drop to avoid
dependency on message ordering, as we do in other tests.
Tom also closed a security bug: we documented that table ownership was

actually implement it.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Allow setting statistics target for extended statistics
When building statistics, we need to decide how many rows to sample and
how accurate the resulting statistics should be. Until now, it was not
possible to explicitly define statistics target for extended statistics
objects, the value was always computed from the per-attribute targets
with a fallback to the system-wide default statistics target.
That's a bit inconvenient, as it ties together the statistics target set
for per-column and extended statistics. In some cases it may be useful
to require larger sample / higher accuracy for extended statics (or the
other way around), but with this approach that's not possible.
So this commit introduces a new command, allowing to specify statistics
target for individual extended statistics objects, overriding the value
derived from per-attribute targets (and the system default).
ALTER STATISTICS stat_name SET STATISTICS target_value;
When determining statistics target for an extended statistics object we
first look at this explicitly set value. When this value is -1, we fall
back to the old formula, looking at the per-attribute targets first and
then the system default. This means the behavior is backwards compatible
with older PostgreSQL releases.

Extended statistics on expressions
Allow defining extended statistics on expressions, not just just on
simple column references. With this commit, expressions are supported
by all existing extended statistics kinds, improving the same types of
estimates. A simple example may look like this:
CREATE TABLE t (a int);
CREATE STATISTICS s ON mod(a,10), mod(a,20) FROM t;
ANALYZE t;
The collected statistics are useful e.g. to estimate queries with those
expressions in WHERE or GROUP BY clauses:
SELECT * FROM t WHERE mod(a,10) = 0 AND mod(a,20) = 0;
SELECT 1 FROM t GROUP BY mod(a,10), mod(a,20);
This introduces new internal statistics kind 'e' (expressions) which is
built automatically when the statistics object definition includes any
expressions. This represents single-expression statistics, as if there
was an expression index (but without the index maintenance overhead).
The statistics is stored in pg_statistics_ext_data as an array of
composite types, which is possible thanks to 79f6a942bd.
CREATE STATISTICS allows building statistics on a single expression, in
which case in which case it's not possible to specify statistics kinds.
A new system view pg_stats_ext_exprs can be used to display expression
statistics, similarly to pg_stats and pg_stats_ext views.
ALTER TABLE ... ALTER COLUMN ... TYPE now treats indexes the same way it
treats indexes, i.e. it drops and recreates the statistics. This means
all statistics are reset, and we no longer try to preserve at least the
functional dependencies. This should not be a major issue in practice,
as the functional dependencies actually rely on per-column statistics,
which were always reset anyway.

Extended statistics on expressions
Allow defining extended statistics on expressions, not just just on
simple column references. With this commit, expressions are supported
by all existing extended statistics kinds, improving the same types of
estimates. A simple example may look like this:
CREATE TABLE t (a int);
CREATE STATISTICS s ON mod(a,10), mod(a,20) FROM t;
ANALYZE t;
The collected statistics are useful e.g. to estimate queries with those
expressions in WHERE or GROUP BY clauses:
SELECT * FROM t WHERE mod(a,10) = 0 AND mod(a,20) = 0;
SELECT 1 FROM t GROUP BY mod(a,10), mod(a,20);
This introduces new internal statistics kind 'e' (expressions) which is
built automatically when the statistics object definition includes any
expressions. This represents single-expression statistics, as if there
was an expression index (but without the index maintenance overhead).
The statistics is stored in pg_statistics_ext_data as an array of
composite types, which is possible thanks to 79f6a942bd.
CREATE STATISTICS allows building statistics on a single expression, in
which case in which case it's not possible to specify statistics kinds.
A new system view pg_stats_ext_exprs can be used to display expression
statistics, similarly to pg_stats and pg_stats_ext views.
ALTER TABLE ... ALTER COLUMN ... TYPE now treats indexes the same way it
treats indexes, i.e. it drops and recreates the statistics. This means
all statistics are reset, and we no longer try to preserve at least the
functional dependencies. This should not be a major issue in practice,
as the functional dependencies actually rely on per-column statistics,
which were always reset anyway.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Local partitioned indexes
When CREATE INDEX is run on a partitioned table, create catalog entries
for an index on the partitioned table (which is just a placeholder since
the table proper has no data of its own), and recurse to create actual
indexes on the existing partitions; create them in future partitions
also.
As a convenience gadget, if the new index definition matches some
existing index in partitions, these are picked up and used instead of
creating new ones. Whichever way these indexes come about, they become
attached to the index on the parent table and are dropped alongside it,
and cannot be dropped on isolation unless they are detached first.
To support pg_dump'ing these indexes, add commands
CREATE INDEX ON ONLY <table>
(which creates the index on the parent partitioned table, without
recursing) and
ALTER INDEX ATTACH PARTITION
(which is used after the indexes have been created individually on each
partition, to attach them to the parent index). These reconstruct prior
database state exactly.

Local partitioned indexes
When CREATE INDEX is run on a partitioned table, create catalog entries
for an index on the partitioned table (which is just a placeholder since
the table proper has no data of its own), and recurse to create actual
indexes on the existing partitions; create them in future partitions
also.
As a convenience gadget, if the new index definition matches some
existing index in partitions, these are picked up and used instead of
creating new ones. Whichever way these indexes come about, they become
attached to the index on the parent table and are dropped alongside it,
and cannot be dropped on isolation unless they are detached first.
To support pg_dump'ing these indexes, add commands
CREATE INDEX ON ONLY <table>
(which creates the index on the parent partitioned table, without
recursing) and
ALTER INDEX ATTACH PARTITION
(which is used after the indexes have been created individually on each
partition, to attach them to the parent index). These reconstruct prior
database state exactly.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump's handling of "special" built-in objects.
We had some pretty ad-hoc handling of the public schema and the plpgsql
extension, which are both presumed to exist in template0 but might be
modified or deleted in the database being dumped.
Up to now, by default pg_dump would emit a CREATE EXTENSION IF NOT EXISTS
command as well as a COMMENT command for plpgsql. The usefulness of the
former is questionable, and the latter caused annoying errors in
non-superuser dump/restore scenarios. Let's instead install a rule that
built-in extensions (identified by having low-numbered OIDs) are not to be
dumped. We were doing it that way already in binary-upgrade mode, so this
just makes regular mode behave the same. It remains true that if someone
has installed a non-default ACL on the plpgsql language, that will get
dumped thanks to the pg_init_privs mechanism. This is more consistent with
the handling of built-in objects of other kinds.
Also, change the very ad-hoc mechanism that was used to avoid dumping
creation and comment commands for the public schema. Instead of hardwiring
a test in _printTocEntry(), make use of the DUMP_COMPONENT_ infrastructure
to mark that schema up-front about what we want to do with it. This has
the visible effect that the public schema won't be mentioned in the output
at all, except for updating its ACL if it has a non-default ACL.
Previously, while it was normally not mentioned, --clean mode would drop
and recreate it, again causing headaches for non-superuser usage. This
change likewise makes the public schema less special and more like other
built-in objects.
If plpgsql, or the public schema, has been removed entirely in the source
DB, that situation won't be reproduced in the destination ... but that
was true before.

87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).

Improve pg_dump's handling of "special" built-in objects.
We had some pretty ad-hoc handling of the public schema and the plpgsql
extension, which are both presumed to exist in template0 but might be
modified or deleted in the database being dumped.
Up to now, by default pg_dump would emit a CREATE EXTENSION IF NOT EXISTS
command as well as a COMMENT command for plpgsql. The usefulness of the
former is questionable, and the latter caused annoying errors in
non-superuser dump/restore scenarios. Let's instead install a rule that
built-in extensions (identified by having low-numbered OIDs) are not to be
dumped. We were doing it that way already in binary-upgrade mode, so this
just makes regular mode behave the same. It remains true that if someone
has installed a non-default ACL on the plpgsql language, that will get
dumped thanks to the pg_init_privs mechanism. This is more consistent with
the handling of built-in objects of other kinds.
Also, change the very ad-hoc mechanism that was used to avoid dumping
creation and comment commands for the public schema. Instead of hardwiring
a test in _printTocEntry(), make use of the DUMP_COMPONENT_ infrastructure
to mark that schema up-front about what we want to do with it. This has
the visible effect that the public schema won't be mentioned in the output
at all, except for updating its ACL if it has a non-default ACL.
Previously, while it was normally not mentioned, --clean mode would drop
and recreate it, again causing headaches for non-superuser usage. This
change likewise makes the public schema less special and more like other
built-in objects.
If plpgsql, or the public schema, has been removed entirely in the source
DB, that situation won't be reproduced in the destination ... but that
was true before.

appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

still quite a bit which remains to be added to provide better code

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

only_dump_test_table => 1,

pg_dump: Properly handle public schema ACLs with --clean
pg_dump has always handled the public schema in a special way when it
comes to the "--clean" option. To wit, we do not drop or recreate the
public schema in "normal" mode, but when we are run in "--clean" mode
then we do drop and recreate the public schema.
When running in "--clean" mode, the public schema is dropped and then
recreated and it is recreated with the normal schema-default privileges
of "nothing". This is unlike how the public schema starts life, which
is to have CREATE and USAGE GRANT'd to the PUBLIC role, and that is what
is recorded in pg_init_privs.
Due to this, in "--clean" mode, pg_dump would mistakenly only dump out
the set of privileges required to go from the initdb-time privileges on
the public schema to whatever the current-state privileges are. If the
privileges were not changed from initdb time, then no privileges would
be dumped out for the public schema, but with the schema being dropped
and recreated, the result was that the public schema would have no ACLs
on it instead of what it should have, which is the initdb-time
privileges.
Practically speaking, this meant that pg_dump with --clean mode dumping
a database where the ACLs on the public schema were not changed from the
default would, upon restore, result in a public schema with *no*
privileges GRANT'd, not matching the state of the existing database
(where the initdb-time privileges would have been CREATE and USAGE to
the PUBLIC role for the public schema).
To fix, adjust the query in getNamespaces() to ignore the pg_init_privs
entry for the public schema when running in "--clean" mode, meaning that
the privileges for the public schema would be dumped, correctly, as if
it was going from a newly-created schema to the current state (which is,
indeed, what will happen during the restore thanks to the DROP/CREATE).
Only the public schema is handled in this special way by pg_dump, no
other initdb-time objects are dropped/recreated in --clean mode.
Back-patch to 9.6 where the bug was introduced.

Improve pg_dump's handling of "special" built-in objects.
We had some pretty ad-hoc handling of the public schema and the plpgsql
extension, which are both presumed to exist in template0 but might be
modified or deleted in the database being dumped.
Up to now, by default pg_dump would emit a CREATE EXTENSION IF NOT EXISTS
command as well as a COMMENT command for plpgsql. The usefulness of the
former is questionable, and the latter caused annoying errors in
non-superuser dump/restore scenarios. Let's instead install a rule that
built-in extensions (identified by having low-numbered OIDs) are not to be
dumped. We were doing it that way already in binary-upgrade mode, so this
just makes regular mode behave the same. It remains true that if someone
has installed a non-default ACL on the plpgsql language, that will get
dumped thanks to the pg_init_privs mechanism. This is more consistent with
the handling of built-in objects of other kinds.
Also, change the very ad-hoc mechanism that was used to avoid dumping
creation and comment commands for the public schema. Instead of hardwiring
a test in _printTocEntry(), make use of the DUMP_COMPONENT_ infrastructure
to mark that schema up-front about what we want to do with it. This has
the visible effect that the public schema won't be mentioned in the output
at all, except for updating its ACL if it has a non-default ACL.
Previously, while it was normally not mentioned, --clean mode would drop
and recreate it, again causing headaches for non-superuser usage. This
change likewise makes the public schema less special and more like other
built-in objects.
If plpgsql, or the public schema, has been removed entirely in the source
DB, that situation won't be reproduced in the destination ... but that
was true before.

Avoid using unsafe search_path settings during dump and restore.
Historically, pg_dump has "set search_path = foo, pg_catalog" when
dumping an object in schema "foo", and has also caused that setting
to be used while restoring the object. This is problematic because
functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run

functions and operators in schema "foo" could capture references meant
to refer to pg_catalog entries, both in the queries issued by pg_dump
and those issued during the subsequent restore run. That could
result in dump/restore misbehavior, or in privilege escalation if a
nefarious user installs trojan-horse functions or operators.
This patch changes pg_dump so that it does not change the search_path
dynamically. The emitted restore script sets the search_path to what
was used at dump time, and then leaves it alone thereafter. Created
objects are placed in the correct schema, regardless of the active
search_path, by dint of schema-qualifying their names in the CREATE
commands, as well as in subsequent ALTER and ALTER-like commands.
Since this change requires a change in the behavior of pg_restore
when processing an archive file made according to this new convention,
bump the archive file version number; old versions of pg_restore will
therefore refuse to process files made with new versions of pg_dump.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Improve pg_dump's handling of "special" built-in objects.
We had some pretty ad-hoc handling of the public schema and the plpgsql
extension, which are both presumed to exist in template0 but might be
modified or deleted in the database being dumped.
Up to now, by default pg_dump would emit a CREATE EXTENSION IF NOT EXISTS
command as well as a COMMENT command for plpgsql. The usefulness of the
former is questionable, and the latter caused annoying errors in
non-superuser dump/restore scenarios. Let's instead install a rule that
built-in extensions (identified by having low-numbered OIDs) are not to be
dumped. We were doing it that way already in binary-upgrade mode, so this
just makes regular mode behave the same. It remains true that if someone
has installed a non-default ACL on the plpgsql language, that will get
dumped thanks to the pg_init_privs mechanism. This is more consistent with
the handling of built-in objects of other kinds.
Also, change the very ad-hoc mechanism that was used to avoid dumping
creation and comment commands for the public schema. Instead of hardwiring
a test in _printTocEntry(), make use of the DUMP_COMPONENT_ infrastructure
to mark that schema up-front about what we want to do with it. This has
the visible effect that the public schema won't be mentioned in the output
at all, except for updating its ACL if it has a non-default ACL.
Previously, while it was normally not mentioned, --clean mode would drop
and recreate it, again causing headaches for non-superuser usage. This
change likewise makes the public schema less special and more like other
built-in objects.
If plpgsql, or the public schema, has been removed entirely in the source
DB, that situation won't be reproduced in the destination ... but that
was true before.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.
This covers both the pg_dump TAP tests in src/bin/pg_dump and those in
src/test/modules/test_pg_dump.

Add TAP tests for pg_dump

defined in the '%pgdump_runs' hash, and then for each test in the

defined for the test under the 'like' and 'unlike' functions, as

While this test suite covers a fair bit of ground (67% of pg_dump.c

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Unified logging system for command-line programs
This unifies the various ad hoc logging (message printing, error
printing) systems used throughout the command-line programs.
Features:
- Program name is automatically prefixed.
- Message string does not end with newline. This removes a common
source of inconsistencies and omissions.
- Additionally, a final newline is automatically stripped, simplifying
use of PQerrorMessage() etc., another common source of mistakes.
- I converted error message strings to use %m where possible.
- As a result of the above several points, more translatable message
strings can be shared between different components and between
frontends and backend, without gratuitous punctuation or whitespace
differences.
- There is support for setting a "log level". This is not meant to be
user-facing, but can be used internally to implement debug or
verbose modes.
- Lazy argument evaluation, so no significant overhead if logging at
some level is disabled.
- Some color in the messages, similar to gcc and clang. Set
PG_COLOR=auto to try it out. Some colors are predefined, but can be
customized by setting PG_COLORS.
- Common files (common/, fe_utils/, etc.) can handle logging much more
simply by just using one API without worrying too much about the
context of the calling program, requiring callbacks, or having to
pass "progname" around everywhere.
- Some programs called setvbuf() to make sure that stderr is
unbuffered, even on Windows. But not all programs did that. This
is now done centrally.
Soft goals:
- Reduces vertical space use and visual complexity of error reporting
in the source code.
- Encourages more deliberate classification of messages. For example,
in some cases it wasn't clear without analyzing the surrounding code
whether a message was meant as an error or just an info.
- Concepts and terms are vaguely aligned with popular logging
frameworks such as log4j and Python logging.
This is all just about printing stuff out. Nothing affects program
flow (e.g., fatal exits). The uses are just too varied to do that.
Some existing code had wrappers that do some kind of print-and-exit,
and I adapted those.
I tried to keep the output mostly the same, but there is a lot of
historical baggage to unwind and special cases to consider, and I
might not always have succeeded. One significant change is that
pg_rewind used to write all error messages to stdout. That is now
changed to stderr.

is now done centrally.
Soft goals:
- Reduces vertical space use and visual complexity of error reporting
in the source code.
- Encourages more deliberate classification of messages. For example,
in some cases it wasn't clear without analyzing the surrounding code
whether a message was meant as an error or just an info.
- Concepts and terms are vaguely aligned with popular logging
frameworks such as log4j and Python logging.
This is all just about printing stuff out. Nothing affects program
flow (e.g., fatal exits). The uses are just too varied to do that.
Some existing code had wrappers that do some kind of print-and-exit,
and I adapted those.
I tried to keep the output mostly the same, but there is a lot of
historical baggage to unwind and special cases to consider, and I
might not always have succeeded. One significant change is that
pg_rewind used to write all error messages to stdout. That is now
changed to stderr.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).
Idea for using the TAP system from Tom, though all of the code is mine.

Improve pg_dump regression tests and code coverage
These improvements bring the lines-of-code coverage of pg_dump.c up to
87.7% (at least using LCOV 1.12, 1.11 seems to differ slightly). Nearly
every function is covered, three of the four which aren't are only
called when talking to older PG instances.
There is more which can, and should, be done here to improve the
coverage but it's past time to see what the buildfarm thinks of this.
What has been added:
- Coverage for many more command-line options
- Use command_fails_like instead of command_exit_is
- Operator classes, operator families
- Text search configuration, templates, parsers, dictionaries
- FDWs, servers, foreign tables
- Materialized views
- Improved Publications / Subscriptions test (though this needs work,
see PG10 open items and tests marked with XXX in 002_pg_dump.pl)
- Unlogged tables
- Partitioned tables
- Additional ACL testing for various object types
There is room for improvement, specifically:
- Various type-based option (alignment, storage, etc)
- Composite type collation
- Extra Procedural language functions (inline, validator)
- Different function options (SRF, Transform, config, security definer,
cost, leakproof)
- OpClass options (default, storage, order by, recheck)
- OpFamily options (order by, recheck)
- Aggregate functions (combinefunc, serialfunc, deserialfunc, etc)
- Text Search parser 'headline'
- Text Search template 'init'
- FDW options (handler, validator, options)
- Server options (type, version, options)
- User mapping options
- Default ACLs for sequences, types
- Security labels
- View circular dependencies (last function that needs coverage)
- Toast table autovacuum options
- Replica identity options
- Independent indexes (plus marking them as clustered on)
- Deferrable / initially deferred constraints
- Independent domain constraints
There's bits of extension pg_dump'ing also not covered, but those will
need to go into test_pg_dump (such as having a filter for config
tables).
Last, but not least, this approximately halves the number of tests run
with 'ok()' by removing the ok()-based checking of if all runs are
covered by each test. Instead, 002_pg_dump.pl will just exit out in
such a case (with a message in the log file). In general, when adding
tests, cover all runs unless there is a very good reason not to (such as
adding a 'catch-all' case). With these changes, the resulting output
and number of "tests" run is actually reduced.

Unified logging system for command-line programs
This unifies the various ad hoc logging (message printing, error

Features:
- Program name is automatically prefixed.
- Message string does not end with newline. This removes a common
source of inconsistencies and omissions.
- Additionally, a final newline is automatically stripped, simplifying
use of PQerrorMessage() etc., another common source of mistakes.
- I converted error message strings to use %m where possible.
- As a result of the above several points, more translatable message
strings can be shared between different components and between
frontends and backend, without gratuitous punctuation or whitespace
differences.
- There is support for setting a "log level". This is not meant to be
user-facing, but can be used internally to implement debug or
verbose modes.
- Lazy argument evaluation, so no significant overhead if logging at
some level is disabled.
- Some color in the messages, similar to gcc and clang. Set
PG_COLOR=auto to try it out. Some colors are predefined, but can be
customized by setting PG_COLORS.
- Common files (common/, fe_utils/, etc.) can handle logging much more
simply by just using one API without worrying too much about the

pass "progname" around everywhere.

Allow db.schema.table patterns, but complain about random garbage.
psql, pg_dump, and pg_amcheck share code to process object name
patterns like 'foo*.bar*' to match all tables with names starting in
'bar' that are in schemas starting with 'foo'. Before v14, any number
of extra name parts were silently ignored, so a command line '\d
foo.bar.baz.bletch.quux' was interpreted as '\d bletch.quux'. In v14,
as a result of commit 2c8726c4b0a496608919d1f78a5abc8c9b6e0868, we
instead treated this as a request for table quux in a schema named
'foo.bar.baz.bletch'. That caused problems for people like Justin
Pryzby who were accustomed to copying strings of the form
db.schema.table from messages generated by PostgreSQL itself and using
them as arguments to \d.
Accordingly, revise things so that if an object name pattern contains
more parts than we're expecting, we throw an error, unless there's
exactly one extra part and it matches the current database name.
That way, thisdb.myschema.mytable is accepted as meaning just
myschema.mytable, but otherdb.myschema.mytable is an error, and so
is some.random.garbage.myschema.mytable.
Mark Dilger, per report from Justin Pryzby and discussion among
various people.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).
Idea for using the TAP system from Tom, though all of the code is mine.

Provide test coverage in pg_dump for default behaviors with compression
By default, the contents generated by the custom and directory dump
formats are compressed. However, with the existing test facility, the
restore program will succeed regardless of whether the dumped output was
compressed or not without checking if anything has been compressed.
This commit implements a portable way to check the contents of the
custom and directory dump formats:
- glob_patterns, that can be defined for each test as an array of
glob()-compilable strings, tracking the contents that should or should
not be compressed. While this is useful to make sure that the table
data is compressed, this also checks that blobs.toc and toc.dat are
never compressed.
- command_like, to execute a command on a dump and check its generated
output. This is used here in correlation with pg_restore -l to check if
the dumps have been compressed or not, depending on if the build
supports gzip, or not.
This hole in the tests has come up when working on 5e73a60, where
compression has to be applied by default, if available, for both dump
formats.
The idea of glob_patterns comes from me, and Georgios has come up with
the design for command_like.

Rewrite pg_dump TAP tests
This reworks how the tests to run are defined. Instead of having to
define all runs for all tests, we define those tests which should pass
(generally using one of the defined broad hashes), add in any which
should be specific for this test, and exclude any specific runs that
shouldn't pass for this test. This ends up removing some 4k+ lines
(more than half the file) but, more importantly, greatly simplifies the
way runs-to-be-tested are defined.
As discussed in the updated comments, for example, take the test which
does CREATE TABLE test_table. That CREATE TABLE should show up in all
'full' runs of pg_dump, except those cases where 'test_table' is
excluded, of course, and that's exactly how the test gets defined now
(modulo a few other related cases, like where we dump only that table,
or we dump the schema it's in, or we exclude the schema it's in):
like => {
%full_runs,
%dump_test_schema_runs,
only_dump_test_table => 1,
section_pre_data => 1, },
unlike => {
exclude_dump_test_schema => 1,
exclude_test_table => 1, }, },
Next, we no longer expect every run to be listed for every test. If a
run is listed in 'like' (directly or through a hash) then it's a 'like',
unless it's listed in 'unlike' in which case it's an 'unlike'. If it
isn't listed in either, then it's considered an 'unlike' automatically.
Lastly, this changes the code to no longer use like/unlike but rather to
use 'ok()' with 'diag()' which allows much more control over what gets
spit out to the screen. Gone are the days of the entire dump being sent
to the console, now you'll just get a couple of lines for each failing
test which say the test that failed and the run that it failed on.

Add TAP tests for pg_dump
This TAP test suite will create a new cluster, populate it based on
the 'create_sql' values in the '%tests' hash, run all of the runs
defined in the '%pgdump_runs' hash, and then for each test in the
'%tests' hash, compare each run's output the the regular expression
defined for the test under the 'like' and 'unlike' functions, as
appropriate.
While this test suite covers a fair bit of ground (67% of pg_dump.c
and quite a bit of the other files in src/bin/pg_dump), there is
still quite a bit which remains to be added to provide better code
coverage. Still, this is quite a bit better than we had, and has
found a few bugs already (note that the CREATE TRANSFORM test is
commented out, as it is currently failing).
Idea for using the TAP system from Tom, though all of the code is mine.
