ce51747673 Remove hstore % text[] operator; use slice() function instead.
David Wheeler, with one small correction by me.

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.

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.

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.

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.)

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...)

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.

33e2e02493 Add CVS version labels to all install/uninstall scripts. 2007-11-13 04:24:29 +00:00

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.

d80d8acbce Support functions for index opclasses should be immutable.
Found by running opr_sanity on contrib modules.

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

3f16647960 Rename function 'isexists' and 'isdefined' to
'exist' and 'defined' accordingly. Old names
are saved not mentioned in docs - for compatibility
with old applications.
