* Reconnect to the right database when using parallel restore with -C. Fixes ↵Andrew Dunstan2009-02-20

* Simplify overcomplicated (and overly restrictive) test to see whether anTom Lane2009-02-20
| | | | | | | | | | | | | | IS NULL condition is rendered redundant by detection of an antijoin. If we know that a join is an antijoin, then *any* Var coming out of its righthand side must be NULL, not only the joining column(s). Also, it's still gonna be null after being passed up through higher joins, whether they're outer joins or not. I was misled by a faulty analogy to reduce_outer_joins() in the original coding. But consider select * from a left join b on a.x = b.y where b.y is null and b.z is null; The first IS NULL condition justifies deciding that the join is an antijoin (if the = is strict) and then the second one is just plain redundant.

* Add an implicit rule %.c -> %.i for running the C preprocessor.Peter Eisentraut2009-02-19
| | | | | I occasionally use this for debugging, and it seems wasteful to have to reinvent this all the time.
* Remove croak and Perl_croak from gettext triggers. While we couldPeter Eisentraut2009-02-19
| | | | | | | | | | | | | selectively mark up their arguments for translation, the Perl xsubpp tool generates a bunch of additional Perl_croak calls that we cannot control, so we'd be creating a confusing mix of translated and untranslated messages of a similar kind. This is something that might deserve a more comprehensive solution later. Also remove _ from gettext triggers, because it wasn't used. Use SPI.c instead of SPI.xs as source file for xgettext, because the .xs format isn't really supported in xgettext.
* Increase NUM_AUXILIARY_PROCS, now that the startup process can co-existHeikki Linnakangas2009-02-19
| | | | | with other auxiliary processes for a short period. As witnessed by buildfarm member dungbeetle.
* Remove the special cases to prevent minus-zero results in float4 and float8Tom Lane2009-02-18
| | | | | | | | | | | | | | unary minus operators. We weren't attempting to prevent minus zero anywhere else; in view of our gradual trend to make the float datatypes more IEEE standard compliant, we should allow minus zero here rather than disallow it elsewhere. We don't, however, expect that all platforms will produce minus zero, so we need to adjust the one affected regression test to allow both results. Per discussion of bug #4660. (In passing, clean up a couple other minor infelicities in float.c.)
* Start background writer during archive recovery. Background writer now performsHeikki Linnakangas2009-02-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | its usual buffer cleaning duties during archive recovery, and it's responsible for performing restartpoints. This requires some changes in postmaster. When the startup process has done all the initialization and is ready to start WAL redo, it signals the postmaster to launch the background writer. The postmaster is signaled again when the point in recovery is reached where we know that the database is in consistent state. Postmaster isn't interested in that at the moment, but that's the point where we could let other backends in to perform read-only queries. The postmaster is signaled third time when the recovery has ended, so that postmaster knows that it's safe to start accepting connections. The startup process now traps SIGTERM, and performs a "clean" shutdown. If you do a fast shutdown during recovery, a shutdown restartpoint is performed, like a shutdown checkpoint, and postmaster kills the processes cleanly. You still have to continue the recovery at next startup, though. Currently, the background writer is only launched during archive recovery. We could launch it during crash recovery as well, but it seems better to keep that codepath as simple as possible, for the sake of robustness. And it couldn't do any restartpoints during crash recovery anyway, so it wouldn't be that useful. log_restartpoints is gone. Use log_checkpoints instead. This is yet to be documented. This whole operation is a pre-requisite for Hot Standby, but has some value of its own whether the hot standby patch makes 8.4 or not. Simon Riggs, with lots of modifications by me.

* Loop calling CallNamedPipe() several times in case it fails,Magnus Hagander2009-02-15

* A couple of marginal performance hacks for the information_schema views:Tom Lane2009-02-14
| | | | | | | | | replace the old recursive-SQL-function implementation of _pg_keysequal() with use of the built-in array containment operators, and change table_constraints' UNION to UNION ALL. Per discussion with Octavio Alvarez. initdb not forced since this doesn't affect results, but you'd need to initdb or reload the information_schema to see the new definitions.
* Fix UNLISTEN to fall out quickly if the current backend has never executedTom Lane2009-02-13
| | | | | | | | | | | | any LISTEN command. This is more important than it used to be because DISCARD ALL invokes UNLISTEN. Connection-pooled applications making heavy use of DISCARD ALL were seeing significant contention for pg_listener, as reported by Matteo Beccati. It seems unlikely that clients using LISTEN would use pooled connections, so this simple tweak seems sufficient, especially since the pg_listener implementation is slated to go away soon anyway. Back-patch to 8.3, where DISCARD ALL was introduced.

* The Czech (cs_CZ) and Slovak (sk_SK) locales sort numbers after letters,Peter Eisentraut2009-02-12
| | | | | | instead of vice versa. Update the regression test expectations to support that. In the plpgsql test, adjust the test data so that this isn't an issue. In the char and varchar tests, add new expected files.

* Don't call SetEnvironmentVariable() when removing an environment variable,Magnus Hagander2009-02-12
| | | | | as this seems to crash on at least some versions of MingW. Our current usage of this function does not require it, so it should be ok to ignore.
* Change ALTER TABLE SET WITHOUT OIDS to rewrite the whole table to physicallyTom Lane2009-02-11
| | | | | | | | | | | | | | | | get rid of the OID column. This eliminates the problem discovered by Heikki back in November that 8.4's suppression of "unnecessary" junk filtering in INSERT/SELECT could lead to an Assert failure, or storing of oids into a table that shouldn't have them if Asserts are off. While that particular problem could have been solved in other ways, it seems likely to be just a forerunner of things to come if we continue to allow tables to contain rows that disagree with the pg_class.relhasoids setting. It's better to make this operation slow than to sacrifice performance or risk bugs in more common code paths. Also, add ALTER TABLE SET WITH OIDS to rewrite the table to add oids. This was a bit more controversial, but in view of the very small amount of extra code needed given the current ALTER TABLE infrastructure, it seems best to eliminate the asymmetry in features.
* Tweak configure to attempt to add -qnoansialias to CFLAGS whenever runningTom Lane2009-02-11
| | | | | | on AIX with a non-gcc compiler. The previous coding would do this only if CC was exactly "xlc"; which is a bad idea, as demonstrated by trouble report from Mihai Criveti.

* Only unset the locale environment when --no-locale is used (the way it wasPeter Eisentraut2009-02-11
| | | | | | presumably designed, but didn't act). This allows running the temp install tests in a non-C locale, thus exercising users' real environments better. Document how to change locales for test runs.

* Update autovacuum to use reloptions instead of a system catalog, forAlvaro Herrera2009-02-09
| | | | | | | | | per-table overrides of parameters. This removes a whole class of problems related to misusing the catalog, and perhaps more importantly, gives us pg_dump support for the parameters. Based on a patch by Euler Taveira de Oliveira, heavily reworked by me.

* Ensure that INSERT ... SELECT into a table with OIDs never copies row OIDsTom Lane2009-02-08
| | | | | | | | from the source table. This could never happen anyway before 8.4 because the executor invariably applied a "junk filter" to rows due to be inserted; but now that we skip doing that when it's not necessary, the case can occur. Problem noted 2008-11-27 by KaiGai Kohei, though I misunderstood what he was on about at the time (the opacity of the patch he proposed didn't help).
