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 --- src/backend/access/gist/gistget.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'src/backend/access/gist/gistget.c') diff --git a/src/backend/access/gist/gistget.c b/src/backend/access/gist/gistget.c index dcb8f2da54b..c69f2887b89 100644 --- a/src/backend/access/gist/gistget.c +++ b/src/backend/access/gist/gistget.c @@ -8,7 +8,7 @@ * Portions Copyright (c) 1994, Regents of the University of California * * IDENTIFICATION - * $PostgreSQL: pgsql/src/backend/access/gist/gistget.c,v 1.57 2006/05/24 11:01:39 teodor Exp $ + * $PostgreSQL: pgsql/src/backend/access/gist/gistget.c,v 1.58 2006/06/28 12:00:14 teodor Exp $ * *------------------------------------------------------------------------- */ @@ -391,7 +391,6 @@ gistindex_keytest(IndexTuple tuple, gistdentryinit(giststate, key->sk_attno - 1, &de, datum, r, p, offset, - IndexTupleSize(tuple) - sizeof(IndexTupleData), FALSE, isNull); /* -- cgit v1.2.3
