The OID generator is global to the instance, but the unicity
checks are local to the tables that use OIDs, including
large objects.
The case when you may have a problem is if moving
large objects from the old instance/old database
to the new instance/new database but the new
database would already have large objects created
before the import. Then you would need to do a merge
rather than just an import.
But if you're merely in the case that other databases in the new
instance have consumed OIDs and some happen to be equal to the ones
you want to import in a new database, that doesn't matter: similar OIDs
won't conflict if they're in different databases or even the same
database but different tables.
Best regards,
