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_interval.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'contrib/btree_gist/btree_interval.c') diff --git a/contrib/btree_gist/btree_interval.c b/contrib/btree_gist/btree_interval.c index b7776295a0e..6f346f94fed 100644 --- a/contrib/btree_gist/btree_interval.c +++ b/contrib/btree_gist/btree_interval.c @@ -129,7 +129,7 @@ gbt_intv_compress(PG_FUNCTION_ARGS) } gistentryinit(*retval, PointerGetDatum(r), entry->rel, entry->page, - entry->offset, 2 * INTERVALSIZE, FALSE); + entry->offset, FALSE); } PG_RETURN_POINTER(retval); @@ -153,7 +153,7 @@ gbt_intv_decompress(PG_FUNCTION_ARGS) gistentryinit(*retval, PointerGetDatum(r), entry->rel, entry->page, - entry->offset, sizeof(intvKEY), FALSE); + entry->offset, FALSE); } PG_RETURN_POINTER(retval); } -- cgit v1.2.3
