The PQftype value is the OID of the row for the type in the system
pg_type catalog.  Try

	SELECT * FROM pg_type WHERE oid = <PQftype result>

BTW: oid's for the predefined types are consistent across installations,
but oid's for user-defined types are not (and shouldn't even be trusted
across a save/reload).
