From 1f7ef548ec2e594fa8766781c490fb5b998ea46b Mon Sep 17 00:00:00 2001 From: Teodor Sigaev Date: Wed, 28 Jun 2006 12:00:14 +0000 Subject: 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 --- contrib/seg/seg.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'contrib/seg/seg.c') diff --git a/contrib/seg/seg.c b/contrib/seg/seg.c index 47ca1b614a..8f0c83c298 100644 --- a/contrib/seg/seg.c +++ b/contrib/seg/seg.c @@ -316,8 +316,8 @@ gseg_picksplit(GistEntryVector *entryvec, float size_l, size_r; int nbytes; - OffsetNumber seed_1 = 0, - seed_2 = 0; + OffsetNumber seed_1 = 1, + seed_2 = 2; OffsetNumber *left, *right; OffsetNumber maxoff; -- cgit v1.2.1
