commit_ts and test_pg_dump were declaring targets before including the
PGXS stanza, which meant that the "all" target customarily defined as
the first (and therefore default target) was not the default anymore.
Fix that by moving those target definitions to after PGXS.
commit_ts was initially good, but I broke it in commit 9def031bd2;
test_pg_dump was born broken, probably copying from commit_ts' mistake.
In passing, fix a comment mistake in test_pg_dump/Makefile.
Backpatch to 9.6.
Noted by Tom Lane.
Previously, if a schema was created by an extension, a normal pg_dump run
(not --binary-upgrade) would summarily skip every object in that schema.
In a case where an extension creates a schema and then users create other
objects within that schema, this does the wrong thing: we want pg_dump
to skip the schema but still create the non-extension-owned objects.
There's no easy way to fix this pre-9.6, because in earlier versions the
"dump" status for a schema is just a bool and there's no way to distinguish
"dump me" from "dump my members". However, as of 9.6 we do have enough
state to represent that, so this is a simple correction of the logic in
selectDumpableNamespace.
In passing, make some cosmetic fixes in nearby code.

This coding pattern creates a race condition, because if an interesting
interrupt happens after we've checked InterruptPending but before we reset
our latch, the latch-setting done by the signal handler would get lost,
and then we might block at WaitLatch in the next iteration without ever
noticing the interrupt condition. You can put the CHECK_FOR_INTERRUPTS
before WaitLatch or after ResetLatch, but not between them.
Aside from fixing the bugs, add some explanatory comments to latch.h
to perhaps forestall the next person from making the same mistake.
In HEAD, also replace gather_readnext's direct call of
HandleParallelMessages with CHECK_FOR_INTERRUPTS. It does not seem clean
or useful for this one caller to bypass ProcessInterrupts and go straight
to HandleParallelMessages; not least because that fails to consider the
InterruptPending flag, resulting in useless work both here
(if InterruptPending isn't set) and in the next CHECK_FOR_INTERRUPTS call
(if it is).
This thinko seems to have been introduced in the initial coding of
storage/ipc/shm_mq.c (commit ec9037df2), and then blindly copied into all
the subsequent parallel-query support logic. Back-patch relevant hunks
to 9.4 to extirpate the error everywhere.

With the refactoring of pg_dump to handle components, getOwnedSeqs needs
to be a bit more intelligent regarding which components to dump when.
Specifically, we can't simply use the owning table's components as the
set of components to dump as the table might only be including certain
components while all components of the sequence should be dumped, for
example, when the table is a member of an extension while the sequence
is not.
Handle this by combining the set of components to be dumped for the
sequence explicitly and those to be dumped for the table when setting
the components to be dumped for the sequence.
Also add a number of regression tests around this to, hopefully, catch
any future changes which break the expected behavior.

To ensure that "make installcheck" can be used safely against an existing
installation, we need to be careful about what global object names
(database, role, and tablespace names) we use; otherwise we might
accidentally clobber important objects. There's been a weak consensus that
test databases should have names including "regression", and that test role
names should start with "regress_", but we didn't have any particular rule
about tablespace names; and neither of the other rules was followed with
any consistency either.
This commit moves us a long way towards having a hard-and-fast rule that
regression test databases must have names including "regression", and that
test role and tablespace names must start with "regress_". It's not
completely there because I did not touch some test cases in rolenames.sql
that test creation of special role names like "session_user". That will
require some rethinking of exactly what we want to test, whereas the intent
of this patch is just to hit all the cases in which the needed renamings
are cosmetic.
There is no enforcement mechanism in this patch either, but if we don't
add one we can expect that the tests will soon be violating the convention
again. Again, that's not such a cosmetic change and it will require
discussion. (But I did use a quick-hack enforcement patch to find these
cases.)

As of 9.6, pg_regress doesn't build unless storage/lwlocknames.h has been
created; but there was nothing forcing that to happen if you just went into
src/test/regress/ and built there. We previously had a similar complaint
about plpython.
To fix in a way that won't break next time we invent a generated header,
make src/backend/Makefile expose a phony target for updating all the
include files it builds, and invoke that before building pg_regress or
plpython. In principle, maybe we ought to invoke that everywhere; but
it would add a lot of usually-useless make cycles, so let's just do it
in the places where people have complained.
I made a couple of cosmetic adjustments in src/backend/Makefile as well,

dumpAccessMethod() didn't get the memo that we now have a bitfield for
the components which should be dumped instead of a simple boolean.
Correct that by checking if the relevant bit is set for each component
being dumped out (and not dumping it out if it isn't set).
This corrects an issue where CREATE ACCESS METHOD commands were being
included in non-binary-upgrades when an extension included an access
method (as the bloom extensions does).
Also add a regression test to make sure that we only dump out the
ACCESS METHOD commands, when they are part of an extension, when doing
a binary upgrade.

All of the other tables used in the query in dumpTable(), which is

Also, use ::regclass (or ::pg_catalog.regclass, where appropriate)

Issues identified by Noah and Alvaro, patch by me.
The test_pg_dump extension doesn't have a C component, so we need
to exclude it from the MSVC build system trying to figure out how
to build it.
Also add a "MODULES" line to the Makefile, as test_extensions has.
Might not be necessary, but seems good to keep things consistent.
Lastly, remove the 'installcheck' line from test_pg_dump, as that
was causing redefinition errors, at least on my box. This also
makes test_pg_dump consistent with how commit_ts is set up.
The Makefile for test_pg_dump shouldn't have a MODULES_big line
because there's no actual compiled bit for that extension. Hopefully
this will fix the Windows buildfarm members which were complaining.
In passing, also add the 'prove_installcheck' bit to the pg_dump and
test_pg_dump Makefiles, to get the buildfarm members to actually run
those tests.
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).

For reasons of sheer brain fade, we (I) was calling systable_endscan()

That's clearly wrong. Move the systable_endscan() down below the tuple

Add a regression test based on Alvaro's testing.
This feature is controlled by a new old_snapshot_threshold GUC. A
value of -1 disables the feature, and that is the default. The
value of 0 is just intended for testing. Above that it is the
number of minutes a snapshot can reach before pruning and vacuum
are allowed to remove dead tuples which the snapshot would
otherwise protect. The xmin associated with a transaction ID does
still protect dead tuples. A connection which is using an "old"
snapshot does not get an error unless it accesses a page modified
recently enough that it might not be able to produce accurate
results.
This is similar to the Oracle feature, and we use the same SQLSTATE
and error message for compatibility.
This introduces a new dependency type which marks an object as depending
on an extension, such that if the extension is dropped, the object
automatically goes away; and also, if the database is dumped, the object
is included in the dump output. Currently the grammar supports this for
indexes, triggers, materialized views and functions only, although the
utility code is generic so adding support for more object types is a
matter of touching the parser rules only.

In the test_slot_timelines test module, we were abusing passing NULL
values which was received as zeroes in x86, but this breaks in ARM
(buildfarm member hamster) by crashing instead. Fix the breakage by
marking these functions as STRICT; the InvalidXid value that was
previously implicit in NULL values (on x86 at least) can now be passed
as 0. Failing to follow the fmgr protocol to check for NULLs beforehand
was causing ARM to fail, as evidenced by segmentation faults in
buildfarm member hamster.
In order to use the new functionality in the test script, use COALESCE
in the right spot to avoid forwarding NULL values.
This was diagnosed from the hamster crash by Craig Ringer, who also
proposed a different patch (checking for NULL values explicitely in the
C function code, and keeping the non-strictness in the C functions).
I decided to go with this approach instead.
When decoding from a logical slot, it's necessary for xlog reading to be
able to read xlog from historical (i.e. not current) timelines;
otherwise, decoding fails after failover, because the archives are in
the historical timeline. This is required to make "failover logical
slots" possible; it currently has no other use, although theoretically
it could be used by an extension that creates a slot on a standby and
continues to replay from the slot when the standby is promoted.
This commit includes a module in src/test/modules with functions to
manipulate the slots (which is not otherwise possible in SQL code) in
order to enable testing, and a new test in src/test/recovery to ensure
that the behavior is as expected.

This makes the psql() method much more capable: it captures both stdout

timeout can now be specified, as can ON_ERROR_STOP behavior; it gained a
new "on_error_die" (defaulting to off) parameter to raise an exception
if there's any problem. Finally, additional parameters to psql can be
passed if there's need for further tweaking.
For convenience, a new safe_psql() method retains much of the old
behavior of psql(), except that it uses on_error_die on, so that
problems like syntax errors in SQL commands can be detected more easily.
Many existing TAP test files now use safe_psql, which is what is really
wanted. A couple of ->psql() calls are now added in the commit_ts
tests, which verify that the right thing is happening on certain errors.
Some ->command_fails() calls in recovery tests that were verifying that

Also add SECURITY_NOFORCE_RLS context to avoid data corruption when
ALTER TABLE .. FORCE ROW SECURITY is being used. The
SECURITY_NOFORCE_RLS security context is used only during referential
integrity checks and is only considered in check_enable_rls() after we
have already checked that the current user is the owner of the relation
(which should always be the case during referential integrity checks).

Reported by Michael Paquier.
This feature lets user code inspect and take action on DDL events.
Whenever a ddl_command_end event trigger is installed, DDL actions
executed are saved to a list which can be inspected during execution of
a function attached to ddl_command_end.
The set-returning function pg_event_trigger_ddl_commands can be used to
list actions so captured; it returns data about the type of command
executed, as well as the affected object. This is sufficient for many
uses of this feature. For the cases where it is not, we also provide a
"command" column of a new pseudo-type pg_ddl_command, which is a
pointer to a C structure that can be accessed by C code. The struct
contains all the info necessary to completely inspect and even
reconstruct the executed command.
There is no actual deparse code here; that's expected to come later.
What we have is enough infrastructure that the deparsing can be done in
an external extension. The intention is that we will add some deparsing
code in a later release, as an in-core extension.
A new test module is included. It's probably insufficient as is, but it
should be sufficient as a starting point for a more complete and

The original security barrier view implementation, on which RLS is
built, prevented all non-leakproof functions from being pushed down to
below the view, even when the function was not receiving any data from
the view. This optimization improves on that situation by, instead of
checking strictly for non-leakproof functions, it checks for Vars being
passed to non-leakproof functions and allows functions which do not
accept arguments or whose arguments are not from the current query level
(eg: constants can be particularly useful) to be pushed down.
As discussed, this does mean that a function which is pushed down might
gain some idea that there are rows meeting a certain criteria based on
the number of times the function is called, but this isn't a
particularly new issue and the documentation in rules.sgml already
addressed similar covert-channel risks. That documentation is updated
to reflect that non-leakproof functions may be pushed down now, if
they meet the above-described criteria.
Author: Dean Rasheed, with a bit of rework to make things clearer,
along with comment and documentation updates from me.
The RLS capability is built on top of the WITH CHECK OPTION
system which was added for auto-updatable views, however, unlike
WCOs on views (which are mandated by the SQL spec to not fire until
after all other constraints and checks are done), it makes much more
sense for RLS checks to happen earlier than constraint and uniqueness
checks.
This patch reworks the structure which holds the WCOs a bit to be
explicitly either VIEW or RLS checks and the RLS-related checks are
done prior to the constraint and uniqueness checks. This also allows
better error reporting as we are now reporting when a violation is due
to a WITH CHECK OPTION and when it's due to an RLS policy violation,
which was independently noted by Craig Ringer as being confusing.
The documentation is also updated to include a paragraph about when RLS
WITH CHECK handling is performed, as there have been a number of
questions regarding that and the documentation was previously silent on
the matter.
Author: Dean Rasheed, with some kabitzing and comment changes by me.
As pointed out by the buildfarm, test_rls_hooks wasn't functioning
properly with a clean installcheck. test_rls_hooks needs to explicitly
load the library with the hooks in it, to allow installcheck to work;
using the --temp-config doesn't help since that isn't used when running
installcheck and it isn't exactly fair to the buildfarm to modify the
installed config prior to calling installcheck.
Also, have test_rls_hooks clean up after itself.
In prepend_row_security_policies(), defaultDeny was always true, so if
there were any hook policies, the RLS policies on the table would just
get discarded. Fixed to start off with defaultDeny as false and then
properly set later if we detect that only the default deny policy exists
for the internal policies.
The infinite recursion detection in fireRIRrules() didn't properly
manage the activeRIRs list in the case of WCOs, so it would incorrectly
report infinite recusion if the same relation with RLS appeared more
than once in the rtable, for example "UPDATE t ... FROM t ...".
Further, the RLS expansion code in fireRIRrules() was handling RLS in
the main loop through the rtable, which lead to RTEs being visited twice
if they contained sublink subqueries, which
prepend_row_security_policies() attempted to handle by exiting early if
the RTE already had securityQuals. That doesn't work, however, since
if the query involved a security barrier view on top of a table with
RLS, the RTE would already have securityQuals (from the view) by the
time fireRIRrules() was invoked, and so the table's RLS policies would
be ignored. This is fixed in fireRIRrules() by handling RLS in a
separate loop at the end, after dealing with any other sublink
subqueries, thus ensuring that each RTE is only visited once for RLS
expansion.
The inheritance planner code didn't correctly handle non-target
relations with RLS, which would get turned into subqueries during
planning. Thus an update of the form "UPDATE t1 ... FROM t2 ..." where
t1 has inheritance and t2 has RLS quals would fail. Fix by making sure
to copy in and update the securityQuals when they exist for non-target
relations.
process_policies() was adding WCOs to non-target relations, which is
unnecessary, and could lead to a lot of wasted time in the rewriter and
the planner. Fix by only adding WCO policies when working on the result
relation. Also in process_policies, we should be copying the USING
policies to the WITH CHECK policies on a per-policy basis, fix by moving
the copying up into the per-policy loop.
Lastly, as noted by Dean, we were simply adding policies returned by the
hook provided to the list of quals being AND'd, meaning that they would
actually restrict records returned and there was no option to have
internal policies and hook-based policies work together permissively (as
all internal policies currently work). Instead, explicitly add support
for both permissive and restrictive policies by having a hook for each
and combining the results appropriately. To ensure this is all done
correctly, add a new test module (test_rls_hooks) to test the various
combinations of internal, permissive, and restrictive hook policies.

Author: Dean Rasheed, though I added the new hooks and test module.
This improves on commit bbfd7edae5 by
making two simple changes:
* pg_attribute_noreturn now takes parentheses, ie pg_attribute_noreturn().
Likewise pg_attribute_unused(), pg_attribute_packed(). This reduces
pgindent's tendency to misformat declarations involving them.
* attributes are now always attached to function declarations, not
definitions. Previously some places were taking creative shortcuts,
which were not merely candidates for bad misformatting by pgindent
but often were outright wrong anyway. (It does little good to put a
noreturn annotation where callers can't see it.) In any case, if
we would like to believe that these macros can be used with non-gcc
compilers, we should avoid gratuitous variance in usage patterns.
I also went through and manually improved the formatting of a lot of
declarations, and got rid of excessively repetitive (and now obsolete
anyway) comments informing the reader what pg_attribute_printf is for.
Right now, there's only one flag, DSM_CREATE_NULL_IF_MAXSEGMENTS,
which suppresses the error that would normally be thrown when the
maximum number of segments already exists, instead returning NULL.
It might be useful to add more flags in the future, such as one to
ignore allocation errors, but I haven't done that here.
Until now __attribute__() was defined to be empty for all compilers but
gcc. That's problematic because it prevents using it in other compilers;
which is necessary e.g. for atomics portability. It's also just
generally dubious to do so in a header as widely included as c.h.
Instead add pg_attribute_format_arg, pg_attribute_printf,
pg_attribute_noreturn macros which are implemented in the compilers that
understand them. Also add pg_attribute_noreturn and pg_attribute_packed,
but don't provide fallbacks, since they can affect functionality.
This means that external code that, possibly unwittingly, relied on
__attribute__ defined to be empty on !gcc compilers may now run into
warnings or errors on those compilers. But there shouldn't be many
occurances of that and it's hard to work around...

To do so, move InitializeLatchSupport() into the new common process
initialization functions, and add a new global variable MyLatch.
MyLatch is usable as soon InitPostmasterChild() has been called
(i.e. very early during startup). Initially it points to a process
local latch that exists in all processes. InitProcess/InitAuxiliaryProcess
then replaces that local latch with PGPROC->procLatch. During shutdown
the reverse happens.
This is primarily advantageous for two reasons: For one it simplifies
dealing with the shared process latch, especially in signal handlers,
because instead of having to check for MyProc, MyLatch can be used
unconditionally. For another, a later patch that makes FEs/BE
communication use latches, now can rely on the existence of a latch,
even before having gone through InitProcess.

check-world failed in a completely clean tree, because src/test/modules
fail to build unless errcodes.h is generated first. To fix this,
install a dependency in src/test/modules' Makefile so that the necessary
file is generated. Even with this, running "make check" within
individual module subdirs will still fail because the dependency is not
considered there, but this case is less interesting and would be messier
to fix.
check-world still failed with the above fix in place, this time because
dummy_seclabel used LOAD to load the dynamic library, which doesn't work
because the @libdir@ (expanded by the makefile) is expanded to the final
install path, not the temporary installation directory used by make
check. To fix, tweak things so that CREATE EXTENSION can be used
instead, which solves the problem because the library path is expanded
by the backend, which is aware of the true libdir.
Rather than have the core security_label regression test depend on the
dummy_seclabel module, have that part of the test be executed by
dummy_seclabel itself directly. This simplifies the testing rig a bit;
in particular it should silence the problems from the MSVC buildfarm
phylum, which haven't yet gotten taught how to install src/test/modules.
This is advance preparation for introducing even more test modules; the
easy solution is to add them to contrib, but that's bloated enough that
it seems a good time to think of something different.
Moved modules are dummy_seclabel, test_shm_mq, test_parser and
worker_spi.
(test_decoding was also a candidate, but there was too much opposition
to moving that one. We can always reconsider later.)
