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/btree_gist/btree_text.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'contrib/btree_gist/btree_text.c') diff --git a/contrib/btree_gist/btree_text.c b/contrib/btree_gist/btree_text.c index 6ab77f86ae7..fa4eb904f50 100644 --- a/contrib/btree_gist/btree_text.c +++ b/contrib/btree_gist/btree_text.c @@ -115,7 +115,7 @@ gbt_bpchar_compress(PG_FUNCTION_ARGS) gistentryinit(trim, d, entry->rel, entry->page, - entry->offset, VARSIZE(DatumGetPointer(d)), TRUE); + entry->offset, TRUE); retval = gbt_var_compress(&trim, &tinfo); } else -- cgit v1.2.3
