AFAIK, all objects that you might need to designate can be identified
using the scheme employed in pg_depend and pg_description: catalog OID,
object OID, subobject number.

It will be rejected. We removed pg_attribute OIDs some time ago,
and we aren't going to put them back without a much better reason than
this. If you need a specific counterargument, here is one: pg_attribute
is normally much the largest catalog. If we required its rows to have
unique OIDs, the probability of collisions after OID-counter wraparound
would be much greater than it is in other catalogs.
