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

Bruce Momjian f3d99d160d Add CVS tag lines to files that were lacking them. 2006-03-11 04:38:42 +00:00
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.

Tom Lane 8a65b820e2 Suppress signed-vs-unsigned-char warnings in contrib. 2005-09-24 19:14:05 +00:00
Tom Lane 368739dca8 Fix bogus assumption that sizeof() produces an int-sized result. 2005-06-20 00:32:22 +00:00
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.

Teodor Sigaev fb13881f42 1 fix various comparing functions 
2 implement gtsvector_out for use with gevel module (debug GiST indexes, http://www.sai.msu.su/~megera/postgres/gist/gevel/)

Tom Lane 380bd04c16 Standardize on using the Min, Max, and Abs macros that are in our c.h file, 
getting rid of numerous ad-hoc versions that have popped up in various
places.  Shortens code and avoids conflict with Windows min() and max()
macros.

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.
