From 6889303531187f7867a5dfad5f5b5ba103f7cdd6 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Wed, 12 Sep 2007 22:10:26 +0000 Subject: Redefine the lp_flags field of item pointers as having four states, rather than two independent bits (one of which was never used in heap pages anyway, or at least hadn't been in a very long time). This gives us flexibility to add the HOT notions of redirected and dead item pointers without requiring anything so klugy as magic values of lp_off and lp_len. The state values are chosen so that for the states currently in use (pre-HOT) there is no change in the physical representation. --- src/backend/access/gist/gistutil.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/backend/access/gist/gistutil.c') diff --git a/src/backend/access/gist/gistutil.c b/src/backend/access/gist/gistutil.c index c09e9249ea3..6d4f31d53b2 100644 --- a/src/backend/access/gist/gistutil.c +++ b/src/backend/access/gist/gistutil.c @@ -8,7 +8,7 @@ * Portions Copyright (c) 1994, Regents of the University of California * * IDENTIFICATION - * $PostgreSQL: pgsql/src/backend/access/gist/gistutil.c,v 1.22 2007/04/09 22:03:57 tgl Exp $ + * $PostgreSQL: pgsql/src/backend/access/gist/gistutil.c,v 1.23 2007/09/12 22:10:25 tgl Exp $ *------------------------------------------------------------------------- */ #include "postgres.h" @@ -42,7 +42,7 @@ gistfillbuffer(Relation r, Page page, IndexTuple *itup, for (i = 0; i < len; i++) { l = PageAddItem(page, (Item) itup[i], IndexTupleSize(itup[i]), - off, LP_USED); + off, false); if (l == InvalidOffsetNumber) elog(ERROR, "failed to add item to index page in \"%s\"", RelationGetRelationName(r)); -- cgit v1.2.3
