This seems hard; would it be better to have the CREATE TYPE use a new OID,
and fixup the refs?

This *may* not be all that hard; there is a currently unused (always NULL)
parameter on the pg_dump ArchiveEntry calls intended for extra
dependencies. For UDTs, we could set the this to be the max OID that
references the type (or a list of OIDs, if we had to), then modify the
pg_restore sort code to check these values if not NULL. ie.
   (TOC2 > TOC1)        iff      (Max(TOC2.OID, TOC2.DEPS) > Max(TOC1.OID, TOC1.DEPS))            OR  (
Max(TOC2.OID,TOC2.DEPS) = Max(TOC1.OID, TOC1.DEPS)                 And TOC1.OID = Max(TOC2.DEPS)                )
 
   Where DEPS is a list of OIDs the TOC entry depends on.

(I *think* that's right...).

Since this will only be used when the args is non-null, this code would
only be activated in the current broken case.
