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/parser/parse_utilcmd.c | 7 ++++--- 1 file changed, 4 insertions(+), 3 deletions(-) (limited to 'src/backend/parser/parse_utilcmd.c') diff --git a/src/backend/parser/parse_utilcmd.c b/src/backend/parser/parse_utilcmd.c index a8aee204c74..aa7c144c941 100644 --- a/src/backend/parser/parse_utilcmd.c +++ b/src/backend/parser/parse_utilcmd.c @@ -158,10 +158,11 @@ transformCreateStmt(CreateStmt *stmt, const char *queryString) * If the target relation name isn't schema-qualified, make it so.
