Also, don't forget about the dump/restore issue. You have to remember
to dump OIDs with "-o" or else all your references will be trashed.

Personally I would avoid it. Adding a serial type almost gives you
the same thing anyway. OIDs are useful in system tables and temporarily
in programs when dealing with tables without primary keys.
