elog calls. Also, we need to contemplate mechanisms for controlling
all this functionality --- eg, how much stuff should appear in the
postmaster log? And what API should libpq expose for it?

Add ORDER BY clauses to a bunch of regression test queries that will
otherwise produce randomly-ordered output in the new regime.
with OPAQUE, as per recent pghackers discussion. I still want to do some
more work on the 'cstring' pseudo-type, but I'm going to commit the bulk
of the changes now before the tree starts shifting under me ...

I sent the CLUSTER patch a few days ago and I think it was missed. I
append it again, this time including the regression test files. For the
committer, please note that you have to cvs add the files as they don't
exist. Maybe add to the parallel and serial schedules also, but I don't
know such stuff.

ERROR: ExecInsert: rejected due to CHECK constraint insert_con
To be like this:
ERROR: ExecInsert: rejected due to CHECK constraint "insert_con" on
"insert_tbl"
Updated regression tests to match.
I got sick of seeing 'rejected due to CHECK constraint "$1" in my log and
not being able to find the bug in our website code...

pg_relcheck is gone; CHECK, UNIQUE, PRIMARY KEY, and FOREIGN KEY
constraints all have real live entries in pg_constraint. pg_depend
exists, and RESTRICT/CASCADE options work on most kinds of DROP;
however, pg_depend is not yet very well populated with dependencies.
(Most of the ones that are present at this point just replace formerly
hardwired associations, such as the implicit drop of a relation's pg_type
entry when the relation is dropped.) Need to add more logic to create
dependency entries, improve pg_dump to dump constraints in place of
indexes and triggers, and add some regression tests.
comments on one of the optimizer functions a lot more
clear, adds a summary of the recent KSQO discussion to the
comments in the code, adds regression tests for the bug with
sequence state Tom fixed recently and another reg. test, and
removes some PostQuel legacy stuff: ExecAppend -> ExecInsert,
ExecRetrieve -> ExecSelect, etc. This was changed because the
elog() messages from this routine are user-visible, so we
should be using the SQL terms.

function body (and other properties) as a function in the language
is created. This generalizes ad hoc code that already existed for
the built-in languages.
The validation now happens after the pg_proc tuple of the new function
is created, so it is possible to define recursive SQL functions.
Add some regression test cases that cover bogus function definition
attempts.
sequence functions how to cope with qualified names. Same code is
also used for int4notin, currtid_byrelname, pgstattuple. Also,
move TOAST tables into special pg_toast namespace.
the parsetree representation. As yet we don't *do* anything with schema
names, just drop 'em on the floor; but you can enter schema-compatible
command syntax, and there's even a primitive CREATE SCHEMA command.
No doc updates yet, except to note that you can now extract a field
from a function-returning-row's result with (foo(...)).fieldname.
in pghackers list. Support for oldstyle internal functions is gone
(no longer needed, since conversion is complete) and pg_language entry
'internal' now implies newstyle call convention. pg_language entry
'newC' is gone; both old and newstyle dynamically loaded C functions
are now called language 'C'. A newstyle function must be identified
by an associated info routine. See src/backend/utils/fmgr/README.
allows fixing problems with operators that expected to be able to
return a NULL, such as the '#' line-segment-intersection operator
that tried to return NULL when the two segments don't intersect.
(See, eg, bug report from 1-Nov-99 on pghackers.) Fix some other
bugs in passing, such as backwards comparison in path_distance().
inputs have been converted to newstyle. This should go a long way towards
fixing our portability problems with platforms where char and short
parameters are passed differently from int-width parameters. Still
more to do for the Alpha port however.
Implement "date/time grand unification".
Transform datetime and timespan into timestamp and interval.
Deprecate datetime and timespan, though translate to new types in gram.y.
Transform all datetime and timespan catalog entries into new types.
Make "INTERVAL" reserved word allowed as a column identifier in gram.y.
Remove dt.h, dt.c files, and retarget datetime.h, datetime.c as utility
routines for all date/time types.
date.{h,c} now deals with date, time types.
timestamp.{h,c} now deals with timestamp, interval types.
nabstime.{h,c} now deals with abstime, reltime, tinterval types.
Make NUMERIC a known native type for purposes of type coersion. Not tested.
from a constraint condition does not violate the constraint (cf. discussion
on pghackers 12/9/99). Implemented by adding a parameter to ExecQual,
specifying whether to return TRUE or FALSE when the qual result is
really NULL in three-valued boolean logic. Currently, ExecRelCheck is
the only caller that asks for TRUE, but if we find any other places that
have the wrong response to NULL, it'll be easy to fix them.
expressions in CREATE TABLE. There is no longer an emasculated expression
syntax for these things; it's full a_expr for constraints, and b_expr
for defaults (unfortunately the fact that NOT NULL is a part of the
column constraint syntax causes a shift/reduce conflict if you try a_expr.
Oh well --- at least parenthesized boolean expressions work now). Also,
stored expression for a column default is not pre-coerced to the column
type; we rely on transformInsertStatement to do that when the default is
actually used. This means "f1 datetime default 'now'" behaves the way
people usually expect it to.
BTW, all the support code is now there to implement ALTER TABLE ADD
CONSTRAINT and ALTER TABLE ADD COLUMN with a default value. I didn't
actually teach ALTER TABLE to call it, but it wouldn't be much work.
* Buffer refcount cleanup (per my "progress report" to pghackers, 9/22).
* Add links to backend PROC structs to sinval's array of per-backend info,
and use these links for routines that need to check the state of all
backends (rather than the slow, complicated search of the ShmemIndex
hashtable that was used before). Add databaseOID to PROC structs.
* Use this to implement an interlock that prevents DESTROY DATABASE of
a database containing running backends. (It's a little tricky to prevent
a concurrently-starting backend from getting in there, since the new
backend is not able to lock anything at the time it tries to look up
its database in pg_database. My solution is to recheck that the DB is
OK at the end of InitPostgres. It may not be a 100% solution, but it's
a lot better than no interlock at all...)
* In ALTER TABLE RENAME, flush buffers for the relation before doing the
rename of the physical files, to ensure we don't get failures later from
mdblindwrt().
* Update TRUNCATE patch so that it actually compiles against current
sources :-(.
You should do "make clean all" after pulling these changes.
here is the patch that includes PL/pgSQL into the build
(currently with make errors ignored) and adds a regression
test for it. A clean build and regression ran fine here.
Can you please apply it?
The tar should be extracted in /usr/local/src/pgsql and
creates the following files:
src/pl/Makefile
called by toplevel GNUmakefile and for now only calls
src/pl/plpgsql/Makefile
src/pl/plpgsql/Makefile
calls src/pl/plpgsql/src/Makefile (here the call to
make ignores build errors - this must be changed
later for the final release).
src/test/regress/input/install_plpgsql.source
SQL script installing PL/pgSQL language in regression
database. Will be modified by .../input/Makefile to
point to correct PGLIB directory where plpgsql.so
gets installed.
src/test/regress/output/install_plpgsql.source
expected output for installation script.
src/test/regress/sql/plpgsql.sql
the main regression test. It tests functions and
triggers written in PL/pgSQL including views that use
supportfunctions in this language.
src/test/regress/expected/plpgsql.out
the expected output for the above regression test.
make_plpgsql.diff
patch that adds some lines to
src/GNUmakefile.in
src/test/regress/expected/Makefile
src/test/regress/input/Makefile
src/test/regress/output/Makefile
src/test/regress/sql/Makefile
src/test/regress/sql/tests
1. Remove the char2, char4, char8 and char16 types from postgresql
2. Change references of char16 to name in the regression tests.
3. Rename the char16.sql regression test to name.sql. 4. Modify
the regression test scripts and outputs to match up.
Might require new regression.{SYSTEM} files...
