But from the point of users' view, it does not prevent "create XXX
comand fails due to Oid wraparounding" problems, no?
Also I am worried about the performance of the per table Oid
generators. Even the system tables going to have that kind of
generators? What would happend if there are 5k tables in a database?
It's not very rare situation in a large installation.
