Personally I think we should just shouldn't allow normal connections for the backend slots added by max_wal_senders. They are internally *added* to max_connections, so limiting that seems perfectly fine to me since the system provides max_connections connections externally. Hm... I wonder how that's managed for 9.4's max_worker_processes.
