Robert Haas	31c47e53aa	Rename hstore => text[] operator to % This is not yet in any released version, so we still have the option to change the name. We may want to reserve the token => in a future release.	16 years ago
Robert Haas	b17129b589	Remove hstore's text[] => text[] operator. This is not yet in any released version, so we still have the option to backtrack. Instead, document hstore(text[], text[]). Per discussion.	16 years ago
Tom Lane	172eacba43	Assorted improvements in contrib/hstore. Remove the 64K limit on the lengths of keys and values within an hstore. (This changes the on-disk format, but the old format can still be read.) Add support for btree/hash opclasses for hstore --- this is not so much for actual indexing purposes as to allow use of GROUP BY, DISTINCT, etc. Add various other new functions and operators. Andrew Gierth	17 years ago
Tom Lane	d94582f4f8	Mark contrib's GiST and GIN opclass support functions as STRICT, for safety. (Note: GiST penalty functions could possibly be non-strict, but none are at present.)	17 years ago
Tom Lane	87b8db3774	Adjust the APIs for GIN opclass support functions to allow the extractQuery() method to pass extra data to the consistent() and comparePartial() methods. This is the core infrastructure needed to support the soon-to-appear contrib/btree_gin module. The APIs are still upward compatible with the definitions used in 8.3 and before, although not with the previous 8.4devel function definitions. catversion bump for changes in pg_proc entries (although these are just cosmetic, since GIN doesn't actually look at the function signature before calling it...) Teodor Sigaev and Oleg Bartunov	17 years ago
Tom Lane	9b5c8d45f6	Push index operator lossiness determination down to GIST/GIN opclass "consistent" functions, and remove pg_amop.opreqcheck, as per recent discussion. The main immediate benefit of this is that we no longer need 8.3's ugly hack of requiring @@@ rather than @@ to test weight-using tsquery searches on GIN indexes. In future it should be possible to optimize some other queries better than is done now, by detecting at runtime whether the index match is exact or not. Tom Lane, after an idea of Heikki's, and with some help from Teodor.	18 years ago
Bruce Momjian	33e2e02493	Add CVS version labels to all install/uninstall scripts.	18 years ago
Bruce Momjian	926bbab448	Make /contrib install/uninstall script consistent: remove transactions use create or replace function make formatting consistent set search patch on first line Add documentation on modifying *.sql to set the search patch, and mention that major upgrades should still run the installation scripts. Some of these issues were spotted by Tom today.	18 years ago
Tom Lane	d80d8acbce	Support functions for index opclasses should be immutable. Found by running opr_sanity on contrib modules.	19 years ago
Tom Lane	0effa088f5	Clean up usage of some deprecated APIs, particularly schema-unsafe usage of RelationNameGetTupleDesc().	19 years ago
Teodor Sigaev	754148d81f	Add GIN support for pg_trgm. From Guillaume Smet <guillaume.smet@gmail.com> with minor editorization by me. Hstore improvements * add operation hstore ? text - excat equivalent of exist() * remove undocumented behaviour of contains operation with NULL value * now 'key'::text=>NULL returns '"key"=>NULL' instead of NULL * Add GIN support for contains and exist operations * Add GiST support for exist operatiion * improve regression tests	19 years ago
Teodor Sigaev	3f16647960	Rename function 'isexists' and 'isdefined' to 'exist' and 'defined' accordingly. Old names are saved not mentioned in docs - for compatibility with old applications. Per discussion http://archives.postgresql.org/pgsql-hackers/2006-10/msg00571.php	20 years ago
Tom Lane	684ad6a92f	Rename contrib contains/contained-by operators to @> and <@, per discussion.	20 years ago
Teodor Sigaev	642194ba0c	Add hstore contrib module. Per discussion http://archives.postgresql.org/pgsql-hackers/2006-08/msg01409.php	20 years ago
