PostgreSQL: Using OID as Primary Key

[Anon]

Hi,

Just wondering if anybody out there could let me know how to use a row's OID as the primary key.

OID PRIMARY KEY, --????

I would prerfer to use the OID as it has less overhead than SERIAL, and there is really no good reason to use SERIAL. If I can't figure it out, then I will have to use:

id SERIAL PRIMARY KEY,

TIF,

Use a serial field. OID is for internal use by PostgreSQL itself; there are too many issues with using OID (not surviving during a dump/restore, etc) to recommend it.
