* Minor improvements to code for converting legacy CREATE CONSTRAINT TRIGGERTom Lane2007-11-04
| | | | | | | | | | | commands into proper foreign-key constraints. Believe the constraint name given in the trigger arguments in preference to the trigger name --- to judge from Olivier Prenant's example, pg_dump must at some time have used the autogenerated trigger name there, though AFAICT no current release branch tip does. Improve the emitted NOTICEs to provide more detail (PK table's name and column names). Handle the case where pg_dump forgot to provide the FROM table (a bug that never did get fixed in 7.0.x apparently). This commit doesn't do anything about the question of what to do with incomplete trigger groups.

* Prevent continuing disk-space bloat when profiling (with PROFILE_PID_DIRTom Lane2007-11-04
| | | | | | | | | | enabled) and autovacuum is on. Since there will be a steady stream of autovac worker processes exiting and dropping gmon.out files, allowing them to make separate subdirectories results in serious bloat; and it seems unlikely that anyone will care about those profiles anyway. Limit the damage by forcing all autovac workers to dump in one subdirectory, PGDATA/gprof/avworker/. Per report from Jšrg Beyer and subsequent discussion.
* Teach CREATE CONSTRAINT TRIGGER to convert old-style foreign keyTom Lane2007-11-04
| | | | | | | | trigger definitions into regular foreign key constraints. This seems necessary given that some people evidently never did get around to running adddepend on their schemas, and without some sort of hack the old definitions will no longer work. Per report from Olivier Prenant and subsequent investigation.
* Ensure that EquivalenceClasses generated from ORDER BY keys contain properTom Lane2007-11-02
| | | | | | | | | RelabelType nodes when the sort key is binary-compatible with the sort operator rather than having exactly its input type. We did this correctly for index columns but not sort keys, leading to failure to notice that a varchar index matches an ORDER BY request. This requires a bit more work in make_sort_from_pathkeys, but not anyplace else that I can find. Per bug report and subsequent discussion.

* simple script to pull together a very small (<500k) tar file that buildsMarc G. Fournier2007-10-30
| | | | | | | | | *just* libpq ... its not perfect, as it pulls in more files then is necessarily required to build, but as it is, it requires one simple patch to configure.in in order to work ... Tested on FreeBSD ... patch for configure.in hasn't been applied, but putting the script in place so that it doesn't get lost ...
* In the previous commit message, I forgot to credit Simon Riggs who providedAlvaro Herrera2007-10-29

* Mention the index name in 'could not create unique index' errors,Tom Lane2007-10-29

* Remove the hack in the grammar that "optimized away" DEFAULT NULL clauses.Tom Lane2007-10-29
| | | | | | | | | | | | | | | Instead put in a test to drop a NULL default at the last moment before storing the catalog entry. This changes the behavior in a couple of ways: * Specifying DEFAULT NULL when creating an inheritance child table will successfully suppress inheritance of any default expression from the parent's column, where formerly it failed to do so. * Specifying DEFAULT NULL for a column of a domain type will correctly override any default belonging to the domain; likewise for a sub-domain. The latter change happens because by the time the clause is checked, it won't be a simple null Const but a CoerceToDomain expression. Personally I think this should be back-patched, but there doesn't seem to be consensus for that on pgsql-hackers, so refraining.
* - Add check of already changed page while replay WAL. This touches onlyTeodor Sigaev2007-10-29
| | | | | | | | | | | | | ginRedoInsert(), because other ginRedo* functions rewrite whole page or make changes which could be applied several times without consistent's loss - Remove check of identifying of corresponding split record: it's possible that replaying of WAL starts after actual page split, but before removing of that split from incomplete splits list. In this case, that check cause FATAL error. Per stress test which reproduces bug reported by Craig McElroy <craig.mcelroy@contegix.com>

* Make pg_dump and friends consistently report both the filename and theTom Lane2007-10-28
| | | | | | errno string when complaining of fopen failures. Per gripe from Bob Pawley, it's not always instantly obvious to the user which name we tried to open.
* Fix a couple of issues with pg_dump's handling of inheritance child tablesTom Lane2007-10-28
| | | | | | | | | | | | | | | | | | that have default expressions different from their parent. First, if the parent table's default expression has to be split out as a separate ALTER TABLE command, we need a dependency constraint to ensure that the child's command is given second. This is because the ALTER TABLE on the parent will propagate to the child. (We can't prevent that by using ONLY on the parent's command, since it's possible that other children exist that should receive the inherited default.) Second, if the child has a NULL default where the parent does not, we have to explicitly say DEFAULT NULL on the child in order for this state to be preserved after reload. (The latter actually doesn't work right because of a backend bug, but that is a separate issue.) Backpatch as far as 8.0. 7.x pg_dump has enough issues with altered tables (due to lack of dependency analysis) that trying to fix this one doesn't seem very productive.
* Change text search parsing rules for hyphenated words so that digit stringsTom Lane2007-10-27
| | | | | | | containing decimal points aren't considered part of a hyphenated word. Sync the hyphenated-word lookahead states with the subsequent part-by-part reparsing states so that we don't get different answers about how much text is part of the hyphenated word. Per my gripe of a few days ago.
* Add some rudimentary tracing code to the default text search parser, to helpTom Lane2007-10-27
| | | | | | in debugging its state-machine rules. Const-ify all the constant tables. Minor other code cleanup, including using "token" rather than "lexeme" to describe the output strings.
* Rename default text search parser's "uri" token type to "url_path",Tom Lane2007-10-27
| | | | | | per recommendation from Alvaro. This doesn't force initdb since the numeric token type in the catalogs doesn't change; but note that the expected regression test output changed.
