From c1d62bfd00f4d1ea0647e12947ca1de9fea39b33 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Sun, 9 Nov 2003 21:30:38 +0000 Subject: Add operator strategy and comparison-value datatype fields to ScanKey. Remove the 'strategy map' code, which was a large amount of mechanism that no longer had any use except reverse-mapping from procedure OID to strategy number. Passing the strategy number to the index AM in the first place is simpler and faster. This is a preliminary step in planned support for cross-datatype index operations. I'm committing it now since the ScanKeyEntryInitialize() API change touches quite a lot of files, and I want to commit those changes before the tree drifts under me. --- src/backend/nodes/copyfuncs.c | 13 ++++++++++++- 1 file changed, 12 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 17b32cd4ab8..c02270fa2e7 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 - * $Header: /cvsroot/pgsql/src/backend/nodes/copyfuncs.c,v 1.265 2003/08/17 23:43:25 tgl Exp $ + * $Header: /cvsroot/pgsql/src/backend/nodes/copyfuncs.c,v 1.266 2003/11/09 21:30:36 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -262,6 +262,17 @@ _copyIndexScan(IndexScan *from) COPY_OIDLIST_FIELD(indxid); COPY_NODE_FIELD(indxqual); COPY_NODE_FIELD(indxqualorig); + /* this can become COPY_NODE_FIELD when intlists are normal objects: */ + { + List *newstrat = NIL; + List *tmp; + + foreach(tmp, from->indxstrategy) + { + newstrat = lappend(newstrat, listCopy(lfirst(tmp))); + } + newnode->indxstrategy = newstrat; + } COPY_SCALAR_FIELD(indxorderdir); return newnode; -- cgit v1.2.3
