Have no idea, probably need to see if someone answers that in response 
to your issue:

0: PostgreSQL DB connection success: host=localhost dbname=coturn 
user=turn password=turn
     connect_timeout=30

List of relations
         Schema |         Name         | Type  |  Owner
         --------+----------------------+-------+----------
    ...
    public | allowed_peer_ip      | table | postgres
    ...
    public | turn_secret          | table | postgres

You are connecting as user turn and trying to access tables owned by 
user postgres.
