Allow the syntax CREATE TYPE foo, with no parameters, to permit explicit
creation of a shell type. This allows a less hacky way of dealing with
the mutual dependency between a datatype and its I/O functions: make a
shell type, then make the functions, then define the datatype fully.
We should fix pg_dump to handle things this way, but this commit just deals
with the backend.
Martijn van Oosterhout, with some corrections by Tom Lane.
