I haven't read the patch, but the behavior I would expect is:

1. If --extension=pattern is given, then extensions matching the
pattern are included in the dump, regardless of other switches.
(Conversely, use of --extension doesn't affect choices about what
other objects are dumped.)

2. Without --extension, the behavior is backward compatible,
ie, dump extensions in an include_everything dump but not
otherwise.

Maybe we could have a separate discussion as to which switches turn
off include_everything, but that seems independent of this patch.
