From 7537f52a00acb0a2be60a90d9ec384c5935a1695 Mon Sep 17 00:00:00 2001 From: Heikki Linnakangas Date: Thu, 4 Dec 2008 11:42:24 +0000 Subject: Utilize the visibility map in autovacuum, too. There was an oversight in the visibility map patch that because autovacuum always sets VacuumStmt->freeze_min_age, visibility map was never used for autovacuum, only for manually launched vacuums. This patch introduces a new scan_all field to VacuumStmt, indicating explicitly whether the visibility map should be used, or the whole relation should be scanned, to advance relfrozenxid. Anti-wraparound vacuums still need to scan all pages. --- src/backend/nodes/copyfuncs.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/backend/nodes/copyfuncs.c') diff --git a/src/backend/nodes/copyfuncs.c b/src/backend/nodes/copyfuncs.c index 3904c484bc9..54358191f5f 100644 --- a/src/backend/nodes/copyfuncs.c +++ b/src/backend/nodes/copyfuncs.c @@ -15,7 +15,7 @@ * Portions Copyright (c) 1994, Regents of the University of California * * IDENTIFICATION - * $PostgreSQL: pgsql/src/backend/nodes/copyfuncs.c,v 1.413 2008/11/24 08:46:03 petere Exp $ + * $PostgreSQL: pgsql/src/backend/nodes/copyfuncs.c,v 1.414 2008/12/04 11:42:23 heikki Exp $ * *------------------------------------------------------------------------- */ @@ -2771,6 +2771,7 @@ _copyVacuumStmt(VacuumStmt *from) COPY_SCALAR_FIELD(analyze); COPY_SCALAR_FIELD(verbose); COPY_SCALAR_FIELD(freeze_min_age); + COPY_SCALAR_FIELD(scan_all); COPY_NODE_FIELD(relation); COPY_NODE_FIELD(va_cols); -- cgit v1.2.3
