I'm working on stand-alone composite types and running into a
reduce/reduce problem with the grammer. Any suggestions would be
appreciated. Here's what I have:

DefineStmt:
CREATE AGGREGATE func_name definition
{
. . .
}
| CREATE TYPE_P qualified_name AS
'(' TableFuncElementList ')'
{
CompositeTypeStmt *n = makeNode(CompositeTypeStmt);
n->typevar = $3;
n->coldeflist = $6;
$$ = (Node *)n;
}

Thanks,

Joe
