I used this trigger to notify table changes via NOTIFY (migrating off RethinkDB)
CREATE OR REPLACE FUNCTION notify_trigger() RETURNS trigger AS $$
DECLARE
channel_name varchar DEFAULT (TG_TABLE_NAME || '_changes');
BEGIN
IF TG_OP = 'INSERT' THEN
PERFORM pg_notify(channel_name, '{"id": "' || NEW.id || '"}');
RETURN NEW;
END IF;
IF TG_OP = 'DELETE' THEN
PERFORM pg_notify(channel_name, '{"id": "' || OLD.id || '"}');
