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/commands/tablespace.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'src/backend/commands/tablespace.c') diff --git a/src/backend/commands/tablespace.c b/src/backend/commands/tablespace.c index cd80c811a92..5ad08314049 100644 --- a/src/backend/commands/tablespace.c +++ b/src/backend/commands/tablespace.c @@ -1050,8 +1050,8 @@ assign_default_tablespace(const char *newval, bool doit, GucSource source) /* * GetDefaultTablespace -- get the OID of the current default tablespace * - * Regular objects and temporary objects have different default tablespaces, - * hence the forTemp parameter must be specified. + * Temporary objects have different default tablespaces, hence the + * relpersistence parameter must be specified. * * May return InvalidOid to indicate "use the database's default tablespace". * @@ -1062,12 +1062,12 @@ assign_default_tablespace(const char *newval, bool doit, GucSource source) * default_tablespace GUC variable. */ Oid -GetDefaultTablespace(bool forTemp) +GetDefaultTablespace(char relpersistence) { Oid result; /* The temp-table case is handled elsewhere */ - if (forTemp) + if (relpersistence == RELPERSISTENCE_TEMP) { PrepareTempTablespaces(); return GetNextTempTableSpace(); -- cgit v1.2.3
