* Assorted improvements in contrib/hstore.Tom Lane2009-09-301-26/+70
| | | | | | | | | | 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.

* Restructure some header files a bit, in particular heapam.h, by removing someAlvaro Herrera2008-05-121-1/+7
| | | | | | | | | | | | unnecessary #include lines in it. Also, move some tuple routine prototypes and macros to htup.h, which allows removal of heapam.h inclusion from some .c files. For this to work, a new header file access/sysattr.h needed to be created, initially containing attribute numbers of system columns, for pg_dump usage. While at it, make contrib ltree, intarray and hstore header files more consistent with our header style.
* Push index operator lossiness determination down to GIST/GIN opclassTom Lane2008-04-141-0/+5
| | | | | | | | | | | "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.

* Support varlena fields with single-byte headers and unaligned storage.Tom Lane2007-04-061-1/+19
| | | | | | | | | This commit breaks any code that assumes that the mere act of forming a tuple (without writing it to disk) does not "toast" any fields. While all available regression tests pass, I'm not totally sure that we've fixed every nook and cranny, especially in contrib. Greg Stark with some help from Tom Lane
* Add GIN support for pg_trgm. From Guillaume Smet <guillaume.smet@gmail.com>Teodor Sigaev2007-03-141-17/+28
| | | | | | | | | | | | 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
* Fix up several contrib modules that were using varlena datatypes in ↵Tom Lane2007-02-281-12/+11
| | | | | | | not-so-obvious ways. I'm not totally sure that I caught everything, but at least now they pass their regression tests with VARSIZE/SET_VARSIZE defined to reverse byte order.
