The original concept of the reg* types was to implement lookups for
cases that are more complicated than "(SELECT oid FROM pg_foo WHERE
fooname = 'whatever')".  As an example, regprocedure would be
somewhere between seriously painful and impossible to do by hand.
But any potentially-schema-qualified object name is complicated
enough to justify having a reg* type, in the original vision.

However, we've broken that of late with regnamespace and regrole.
regdatabase would be of exactly the same complexity as those
cases.  So I don't see a reason to object, if you think it's
worth the trouble.
