And then after giving a bit more thought, I don't recommend to go
with this approach, because it breaks an established convention that
objects with unknown name is perfectly OK and shown with the null
oid.

In other words, I'd suggest to use the "second best" one I gave in
the message I am responding to.

Thanks.
