Aside from any consistency arguments, this is logically necessary because the I/O functions for these types also handle numeric OID values. Without a quoting rule it is impossible to distinguish numeric OIDs from role or namespace names that happen to contain only digits. Also change the to_regrole and to_regnamespace functions to dequote their arguments. While not logically essential, this seems like a good idea since the other to_reg* functions do it. Anyone who really wants raw lookup of an uninterpreted name can fall back on the time-honored solution of (SELECT oid FROM pg_namespace WHERE nspname = whatever).
