From 5f7b58fad8f45c69bb67944779dce67e2f481995 Mon Sep 17 00:00:00 2001 From: Robert Haas Date: Mon, 13 Dec 2010 12:34:26 -0500 Subject: Generalize concept of temporary relations to "relation persistence". This commit replaces pg_class.relistemp with pg_class.relpersistence; and also modifies the RangeVar node type to carry relpersistence rather than istemp. It also removes removes rd_istemp from RelationData and instead performs the correct computation based on relpersistence. For clarity, we add three new macros: RelationNeedsWAL(), RelationUsesLocalBuffers(), and RelationUsesTempNamespace(), so that we can clarify the purpose of each check that previous depended on rd_istemp. This is intended as infrastructure for the upcoming unlogged tables patch, as well as for future possible work on global temporary tables. --- src/backend/nodes/makefuncs.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/backend/nodes/makefuncs.c') diff --git a/src/backend/nodes/makefuncs.c b/src/backend/nodes/makefuncs.c index 4b268f3c6b3..f06f73bd6ac 100644 --- a/src/backend/nodes/makefuncs.c +++ b/src/backend/nodes/makefuncs.c @@ -15,6 +15,7 @@ */ #include "postgres.h" +#include "catalog/pg_class.h" #include "catalog/pg_type.h" #include "nodes/makefuncs.h" #include "nodes/nodeFuncs.h" @@ -378,7 +379,7 @@ makeRangeVar(char *schemaname, char *relname, int location) r->schemaname = schemaname; r->relname = relname; r->inhOpt = INH_DEFAULT; - r->istemp = false; + r->relpersistence = RELPERSISTENCE_PERMANENT; r->alias = NULL; r->location = location; -- cgit v1.2.3
