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/access/heap/pruneheap.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/backend/access/heap/pruneheap.c') diff --git a/src/backend/access/heap/pruneheap.c b/src/backend/access/heap/pruneheap.c index ee5f38fccd..d1b08b3a8b 100644 --- a/src/backend/access/heap/pruneheap.c +++ b/src/backend/access/heap/pruneheap.c @@ -233,7 +233,7 @@ heap_page_prune(Relation relation, Buffer buffer, TransactionId OldestXmin, /* * Emit a WAL HEAP_CLEAN record showing what we did */ - if (!relation->rd_istemp) + if (RelationNeedsWAL(relation)) { XLogRecPtr recptr; -- cgit v1.2.1
