relation_expr allows specification of "foo *" and "ONLY foo", and is
appropriate for ALTER commands that can recurse to child tables.
qualified_name is appropriate for the ones that are inherently
nonrecursive.
I'm entirely prepared to believe that some of them are misclassified in
the grammar ... you see any problems?
