The system type OIDs are stable.  User-defined types would probably have
a new OID after a dump and reload.

I would not recommend relying on compiled-in OID knowledge for any types
other than the system-defined datatypes.  If you expect to have to deal
with user-defined types, it's best to cache the results of pg_type
lookups at the client end.  You need not worry about OIDs changing
during a single client connection.
