Server always returns json which contains some status of postgres: * instance type: master/slave * xlog location for master * xlog received_location, replayed_location This server could be used by haproxy GET / returns 200 if there is postgres master behind governor. GET /slave returns 200 is there is postgres slave behind governor In all other cases it returns 503 Currently server always listening on 0.0.0.0:8080, but it should be configurable. In the next versions this rest api could also report some status of etcd and could be used by is_healthiest_node method
