This is your solution. Do oyu use OID anywhere within your application. If
not (you shouldn't be) create all table "without oids". If you stop using
OIDs so rapidly, your problems should go away.

Postgresql uses OIDs for tables and triggers internally. If you don't need
OIDs within your data tables you should be able to reduce your OID usage
considerably.
