In general, the solution for edge-case restore selection needs is to
make a list of the dump's contents with "pg_restore -l", edit out what
you don't want using any method you like, then use the edited list with
"pg_restore -L".

While I'd be in favor of improving pg_restore to accept wild-card
patterns, I'm very hesitant to start inventing new kinds of selection
switches for it.  The interactions between such switches would be a
mess.
