I would suggest putting this info in a separate table, pg_change.  It 
would have oid, catalog, user_changed, changed_on.  That way we could 
simply keep the data for all objects which have an OID.

This would also supposedly allow us to track drops if we wanted.

We'd have to check on overhead of this, though, and maybe make it a GUC 
to track it.

This would also be tremendously useful to suppliment replication systems.
