From: "Martin J. Laubach" <mjl@CSlab.tuwien.ac.at> Subject: [HACKERS] Patch: set date to euro/us postgres/iso/sql Here a patch that implements a SET date for use by the datetime stuff. The syntax is SET date TO 'val[,val,...]' where val is us (us dates), euro (european dates), postgres, iso or sql. Thomas is working on the integration in his datetime module. I just needed to get the patch out before it went stale :)

Merge the last few variable.c configuration variables into the generic GUC support. It's now possible to set datestyle, timezone, and client_encoding from postgresql.conf and per-database or per-user settings. Also, implement rollback of SET commands that occur in a transaction that later fails. Create a SET LOCAL var = value syntax that sets the variable only for the duration of the current transaction. All per previous discussions in pghackers.

Repair problem identified by Olivier Prenant: ALTER DATABASE SET search_path should not be too eager to reject paths involving unknown schemas, since it can't really tell whether the schemas exist in the target database. (Also, when reading pg_dumpall output, it could be that the schemas don't exist yet, but eventually will.) ALTER USER SET has a similar issue. So, reduce the normal ERROR to a NOTICE when checking search_path values for these commands. Supporting this requires changing the API for GUC assign_hook functions, which causes the patch to touch a lot of places, but the changes are conceptually trivial.

#ifndef VARIABLE_H
The heralded `Grand Unified Configuration scheme' (GUC) That means you can now set your options in either or all of $PGDATA/configuration, some postmaster option (--enable-fsync=off), or set a SET command. The list of options is in backend/utils/misc/guc.c, documentation will be written post haste. pg_options is gone, so is that pq_geqo config file. Also removed were backend -K, -Q, and -T options (no longer applicable, although -d0 does the same as -Q). Added to configure an --enable-syslog option. changed all callers from TPRINTF to elog(DEBUG)

extern const char *show_timezone(void);
Switch over to using the src/timezone functions for formatting timestamps displayed in the postmaster log. This avoids Windows-specific problems with localized time zone names that are in the wrong encoding, and generally seems like a good idea to forestall other potential platform-dependent issues. To preserve the existing behavior that all backends will log in the same time zone, create a new GUC variable log_timezone that can only be changed on a system-wide basis, and reference log-related calculations to that zone instead of the TimeZone variable. This fixes the issue reported by Hiroshi Saito that timestamps printed by xlog.c startup could be improperly localized on Windows. We still need a simpler patch for that problem in the back branches, however.
