That's fine.  If people want a mechanism that allows changing the other
pg_dump options that are not related to object filtering, they can
implement a configuration file for that.

Sure.  That's not part of this patch.

Keep in mind that this patch is not intended to help pgAdmin
specifically.  It would be great if pgAdmin uses the functionality
implemented here, but if they decide not to, that's not terrible.  They
have survived decades without a pg_dump configuration file; they still
can.

There are several votes in this thread for pg_dump to gain functionality
to filter objects based on a simple specification -- particularly one
that can be written using shell pipelines.  This patch gives it.

That was discussed upthread and led nowhere.
