Column definitions look and act the same. The point of the change is to
not accept COLLATE in all the places where type names are used that are
*not* column definition lists. The original patch accepted nonsense like
create cast (text collate "C" as text collate "de_DE") with ...
and we'd have had to do quite a lot of additional hacking to plug those
holes.
