I was thinking that the CREATE needs to insert index entries, which
depends on having the datatype-specific procs that will be called by
the index access method.  (Not sure if oideq is actually one of the
ones used by any of the indexes on pg_proc, but you get my drift.)

If I had some spare time I'd try it in a junk database...
