Is there any fundamental or philosophical reason why a foreign table
can't accept arguments? Should that be a TODO?
Right now, to accept arguments to a from-clause item, you have to use an
SRF, which is much more limited than a foreign table. If foreign tables
could accept arguments, then SRFs could just be a simplified special
case of foreign tables.
I looked for some previous discussions on this topic and nothing turned
up.
