How exactly do you propose to determine that the OID is free?
If the requested OID is greater than the current OID counter, how
will you prevent a future conflict?
There's no inherent problem in forcing a particular choice of OID;
initdb does it on every run. The trick is to avoid a conflict of
My own feeling is that the current LO setup is fundamentally flawed
by its reliance on specific OID values, and that the right answer is
to find a way to avoid that. contrib/lo might provide some food for
thought here (although it's clearly not the whole answer either).
