Convert contrib modules to use the extension facility. This isn't fully tested as yet, in particular I'm not sure that the "foo--unpackaged--1.0.sql" scripts are OK. But it's time to get some buildfarm cycles on it. sepgsql is not converted to an extension, mainly because it seems to require a very nonstandard installation process.

Add missing /contrib files to CVS. 2000-06-16 03:05:22 +08:00
Avoid use of CREATE OR REPLACE FUNCTION in extension installation files. It was never terribly consistent to use OR REPLACE (because of the lack of comparable functionality for data types, operators, etc), and experimentation shows that it's now positively pernicious in the extension world. We really want a failure to occur if there are any conflicts, else it's unclear what the extension-ownership state of the conflicted object ought to be. Most of the time, CREATE EXTENSION will fail anyway because of conflicts on other object types, but an extension defining only functions can succeed, with bad results. 2011-02-14 10:24:14 +08:00			`CREATE FUNCTION timetravel()`

Update /contrib for "autocommit TO 'on'". Create objects in public schema. Make spacing/capitalization consistent. Remove transaction block use for object creation. Remove unneeded function GRANTs. 2002-10-19 02:41:22 +08:00			`AS 'MODULE_PATHNAME'`
Clean up CREATE FUNCTION syntax usage in contrib and elsewhere, in particular get rid of single quotes around language names and old WITH () construct. 2006-02-28 00:09:50 +08:00			`LANGUAGE C;`

Here is 4 file in tgz: the new timetravel.c, new timetravel.README (cut from spi/README and modified), modified timetravel.sql.in and modified timetravel.example. Features: - optionally 3 parameter for insert/update/delete user name - work with CREATE UNIQUE INDEX ixxx on table xxx (unique_field,time_off); (the original version was work with unique index on 6.5.0-6.5.3, and not work on 7.3.2,7.3.3) (before 6.5.0 and between 6.5.3 and 7.3.2 I dont know) - get_timetravel(tablename) function for check timetravel-status. - timetravel trigger not change oid of the active record. (it is not a good feature, because the old version is automatice prevent the paralel update with "where oid=nnn") B?jthe Zolt?n 2003-07-27 12:51:45 +08:00
