i think in 8.1

it's not a good idea to do what you want to

The preferred way is to not use OID's in user tables... but AFAICS,
you will have no problem if you simply let them there (there is no
need for ALTERing and DUMPing)... i don't know if it will be a
reduction in the space if you don't have OIDs, will be?
