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/pg_trgm/trgm_gist.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'contrib/pg_trgm/trgm_gist.c') diff --git a/contrib/pg_trgm/trgm_gist.c b/contrib/pg_trgm/trgm_gist.c index 4c33a45a229..bfb92336d7d 100644 --- a/contrib/pg_trgm/trgm_gist.c +++ b/contrib/pg_trgm/trgm_gist.c @@ -103,7 +103,7 @@ gtrgm_compress(PG_FUNCTION_ARGS) retval = (GISTENTRY *) palloc(sizeof(GISTENTRY)); gistentryinit(*retval, PointerGetDatum(res), entry->rel, entry->page, - entry->offset, res->len, FALSE); + entry->offset, FALSE); } else if (ISSIGNKEY(DatumGetPointer(entry->key)) && !ISALLTRUE(DatumGetPointer(entry->key))) @@ -126,7 +126,7 @@ gtrgm_compress(PG_FUNCTION_ARGS) retval = (GISTENTRY *) palloc(sizeof(GISTENTRY)); gistentryinit(*retval, PointerGetDatum(res), entry->rel, entry->page, - entry->offset, res->len, FALSE); + entry->offset, FALSE); } PG_RETURN_POINTER(retval); } -- cgit v1.2.3
