There's been disagreement for a long time over whether userids should be
OIDs or ints. If you want to introduce consistency then it's going to
take a lot more than a one-line patch. (First you'll need to convince
the partisans involved which answer is the right one.)

Not as long as OID is 4 bytes.
I'd recommend not making any piecemeal changes, especially not when
there's not yet a consensus which way to converge.
