Even more to the point is that some of them, like PGPORT, are highly
likely to be set in a server's environment to point to the server
itself. It would be extremely dangerous to automatically try to start
replication just because we find those set. In fact, I would argue that
we should fix things so that any such variables inherited from the
server environment are intentionally *NOT* used for making SR
connections.
