I'm afriad you're not going to have a choice..  I would recommend
creating a mapping from the old IDs to the new ones as part of this
upgrade, to keep the historical information.  Guess it's not nice to
point this out- but you really shouldn't have ever used OIDs for
something external to PG (or even internally, really). :)
