If we do this, and default OIDs to "on", honestly, where's the
problem? If the DBA does nothing, things work as before (with
potential OID wraparound issues). If you want to avoid/minimize the
issues, turn off OIDs on your large tables, and write/fix your code to
cope.

(5) [this was suggested earlier] Create separate spaces for "system"
and "user" OIDs. This requires a similar mechanism to (3), but may be
somewhat easier.
