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
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

Teodor Sigaev	1f7ef548ec	Changes ... * new split algorithm (as proposed in http://archives.postgresql.org/pgsql-hackers/2006-06/msg00254.php) * possible call pickSplit() for second and below columns * add spl_(l|r)datum_exists to GIST_SPLITVEC - pickSplit should check its values to use already defined spl_(l|r)datum for splitting. pickSplit should set spl_(l|r)datum_exists to 'false' (if they was 'true') to signal to caller about using spl_(l|r)datum. * support for old pickSplit(): not very optimal but correct split * remove 'bytes' field from GISTENTRY: in any case size of value is defined by it's type. * split GIST_SPLITVEC to two structures: one for using in picksplit and second - for internal use. * some code refactoring * support of subsplit to rtree opclasses TODO: add support of subsplit to contrib modules	19 years ago
Neil Conway	8e5a10d46c	This patch makes the error message strings throughout the backend ... more compliant with the error message style guide. In particular, errdetail should begin with a capital letter and end with a period, whereas errmsg should not. I also fixed a few related issues in passing, such as fixing the repeated misspelling of "lexeme" in contrib/tsearch2 (per Tom's suggestion).	20 years ago
Tom Lane	33feb55c47	Replace bitwise looping with bytewise looping in hemdistsign and ... sizebitvec of tsearch2, as well as identical code in several other contrib modules. This provided about a 20X speedup in building a large tsearch2 index ... didn't try to measure its effects for other operations. Thanks to Stephan Vollmer for providing a test case.	20 years ago

Neil Conway	36ab600511	Cleanup of GiST extensions in contrib/: now that we always invoke GiST ... methods in a short-lived memory context, there is no need for GiST methods to do their own manual (and error-prone) memory management.	20 years ago

Teodor Sigaev	cbfa4092bb	trgm - Trigram matching for PostgreSQL ... -------------------------------------- The pg_trgm contrib module provides functions and index classes for determining the similarity of text based on trigram matching.	21 years ago
Teodor Sigaev	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.	22 years ago
