Have no idea, probably need to see if someone answers that in response
to your issue:
https://github.com/coturn/coturn/issues/484

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.
