Sure, but the question is whether that incremental gain in capability
is worth the extra logical complexity. I'm inclined to think that many
more users would get burned by the complexity than would have use for it.
Considering that we've gotten along this long with only the most
primitive selection capabilities in pg_dump, it doesn't seem like
there's an enormous demand for highly refined capabilities.
(And I agree with David's comment that it might be better to reserve
such behavior for a configuration file than to put it on the command
line.)
