I kinda like that, because it makes the behavior completely independent
of switch ordering, which seems like a good property to preserve.
Anyone else have an opinion pro or con?

Well, pg_dump already has a --blobs switch, which has been a no-op
(because now the default) since 8.1, but it's still in the switch
parser. It wouldn't take much to revive it for the purpose of causing
blobs to be dumped even when there's an inclusion switch. As for PLs,
I'm not really too worried about dumping them per se (since it's usually
easy enough to create the ones you're using). The functionality we're
really lacking there is the "--include-dependencies" switch that was
discussed upthread ... which I think is a fine idea but should wait for
8.3.
