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.	2008-04-14 17:05:34 +00:00
Teodor Sigaev	ef770cbb69	Fixes from Janko Richter <jankorichter@yahoo.de> ... - Fix wrong index results on text, char, varchar for multibyte strings - Fix some SIGFPE signals - Add support for infinite timestamps - Because of locale settings, btree_gist can not be a prefix index anymore (for text). Each node holds now just the lower and upper boundary.	2005-07-01 13:44:56 +00:00
Neil Conway	36ab600511	Cleanup of GiST extensions in contrib/: now that we always invoke GiST ... methods in a short-lived memory context, there is no need for GiST methods to do their own manual (and error-prone) memory management.	2005-05-21 12:08:06 +00:00
Neil Conway	8d6e9bca37	This patch makes some minor style cleanups to contrib/btree_gist: remove ... the "extern" keyword from function definitions, reorganize some PG_GETARG_XXX() usage, and similar.	2005-05-12 00:39:37 +00:00
