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.)

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.

f2c064afcb Cleanup vectors of GISTENTRY and eliminate problem with 64-bit strict-aligned
boxes. Change interface to user-defined GiST support methods union and
picksplit. Now instead of bytea struct it used special GistEntryVector
structure.

f85f43dfb5 Backend support for autocommit removed, per recent discussions. The
only remnant of this failed experiment is that the server will take
SET AUTOCOMMIT TO ON.  Still TODO: provide some client-side autocommit
logic in libpq.

b663f3443b Add a bunch of pseudo-types to replace the behavior formerly associated
with OPAQUE, as per recent pghackers discussion.  I still want to do some
more work on the 'cstring' pseudo-type, but I'm going to commit the bulk
of the changes now before the tree starts shifting under me ...
