I don't think you are being very clear about what feature you are
talking about. The feature that Jeevan has implemented is pushing
aggregates to the remote side when postgres_fdw is in use. The
feature you are talking about is evidently something else, but you
haven't really said what it is. Or not in a way that I can
understand.
