I wonder how this plays with pg_dump, and in particular whether it
breaks the optimizations that a45c78e32 installed for large numbers
of large objects.  The added test cases seem to go out of their way
to leave no trace behind that the pg_dump/pg_upgrade tests might
encounter.

I think you broke psql's \ddp, too.  And some other places; grepping
for DEFACLOBJ_NAMESPACE finds other oversights.

On the whole I find this proposed feature pretty unexciting
and dubiously worthy of the implementation/maintenance effort.
