From 060baf27844163c0874c72d7baf08d3bf9a8ffce Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Thu, 30 Jul 2009 02:45:38 +0000 Subject: Merge the Constraint and FkConstraint node types into a single type. This was foreseen to be a good idea long ago, but nobody had got round to doing it. The recent patch for deferred unique constraints made transformConstraintAttrs() ugly enough that I decided it was time. This change will also greatly simplify parsing of deferred CHECK constraints, if anyone ever gets around to implementing that. While at it, add a location field to Constraint, and use that to provide an error cursor for some of the constraint-related error messages. --- src/backend/nodes/nodeFuncs.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'src/backend/nodes/nodeFuncs.c') diff --git a/src/backend/nodes/nodeFuncs.c b/src/backend/nodes/nodeFuncs.c index 4dc9bd4bbf7..61c0e21db08 100644 --- a/src/backend/nodes/nodeFuncs.c +++ b/src/backend/nodes/nodeFuncs.c @@ -8,7 +8,7 @@ * * * IDENTIFICATION - * $PostgreSQL: pgsql/src/backend/nodes/nodeFuncs.c,v 1.41 2009/07/16 06:33:42 petere Exp $ + * $PostgreSQL: pgsql/src/backend/nodes/nodeFuncs.c,v 1.42 2009/07/30 02:45:37 tgl Exp $ * *------------------------------------------------------------------------- */ @@ -903,6 +903,9 @@ exprLocation(Node *expr) case T_TypeName: loc = ((TypeName *) expr)->location; break; + case T_Constraint: + loc = ((Constraint *) expr)->location; + break; case T_XmlSerialize: /* XMLSERIALIZE keyword should always be the first thing */ loc = ((XmlSerialize *) expr)->location; -- cgit v1.2.3
