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	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	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	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.	23 years ago
