Ugh. Definitely an oversight. Don't suppose you want to think about
pulling the name out of the DROP command ;-) ?

Hardly --- for instance, people using large objects have no other
choice.
You can *not* change pg_restore in a way that will make it impossible
for such people to restore their dumps (and no, I don't think it will
fly to tell someone after the fact they should have used 7.5 pg_dump...)
Maybe it's sufficient to have a backwards-compatibility mode in which
the SET SESSION AUTH commands still get issued same-as-ever. In fact,
you could just automatically do that if you see the archive version is
too old to have ALTER OWNER support.
On the whole though, I think editing the DROP commands might be the best
way. Are there any cases where that would actually not work?
