This seems like a handy addition. What I've done in cases similar to
this was to use `grep -f` on the output of `pg_dump -l` to create a
file suitable for `pg_dump -L`, or mash them together like this:

    pg_restore -L <(pg_dump -l /path/to/dumpfile | grep -f /path/to/listfile) -d new_db /path/to/dumpfile

That's a lot of shell magic and obscure corners of commands to expect
people to use.

Would it make sense to expand this patch to handle other objects?

Best,
David.
