Tom Lane	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.

Bruce Momjian	d747140279	8.4 pgindent run, with new combined Linux/FreeBSD/MinGW typedef list ... provided by Andrew.	17 years ago
Alvaro Herrera	f8c4d7db60	Restructure some header files a bit, in particular heapam.h, by removing some ... 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.	18 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	5f0bf6cb0d	Run pgindent on remaining files now that LOOPBYTE is a usable macro.	18 years ago
Bruce Momjian	224f91f66d	Modify LOOPBYTE/LOOPBIT macros to be more logical; rather than have the ... for() body passed as a parameter, make the macros act as simple headers to code blocks. This allows pgindent to be run on these files.	18 years ago
Tom Lane	3e23b68dac	Support varlena fields with single-byte headers and unaligned storage. ... 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	19 years ago
Teodor Sigaev	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	19 years ago
Tom Lane	9f652d430f	Fix up several contrib modules that were using varlena datatypes in 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.	19 years ago
Bruce Momjian	f99a569a2e	pgindent run for 8.2.	19 years ago
Teodor Sigaev	642194ba0c	Add hstore contrib module. ... Per discussion http://archives.postgresql.org/pgsql-hackers/2006-08/msg01409.php	19 years ago
