In order to understand how to use Postgresql-11 with Coturn, https://github.com/coturn/coturn , I created a postgresql-11 dabatase using /usr/local/share/turnserver/schema.sql  :

     CREATE TABLE turnusers_lt (
         realm varchar(127) default '',
         name varchar(512),
         hmackey char(128),
         PRIMARY KEY (realm,name)

     CREATE TABLE turn_secret (
             realm varchar(127) default '',
             value varchar(256),
             primary key (realm,value)
     );

     CREATE TABLE allowed_peer_ip (
             realm varchar(127) default '',
             ip_range varchar(256),
             primary key (realm,ip_range)
     );

     CREATE TABLE denied_peer_ip (
             realm varchar(127) default '',
             ip_range varchar(256),
             primary key (realm,ip_range)
     );

     CREATE TABLE turn_origin_to_realm (
             origin varchar(127),
             realm varchar(127),
             primary key (origin)
     );

     CREATE TABLE turn_realm_option (
             realm varchar(127) default '',
             opt varchar(32),
             value varchar(128),
             primary key (realm,opt)
     );

     CREATE TABLE oauth_key (
             kid varchar(128),
             ikm_key varchar(256),
             timestamp bigint default 0,
             lifetime integer default 0,
             as_rs_alg varchar(64) default '',
             realm varchar(127),
             primary key (kid)
     );

But these are the tables of coturndb :

     coturn=# \dt
                     List of relations
          Schema |         Name         | Type  |  Owner
         --------+----------------------+-------+----------
          public | admin_user           | table | postgres
          public | allowed_peer_ip      | table | postgres
          public | denied_peer_ip       | table | postgres
          public | oauth_key            | table | postgres
          public | turn_origin_to_realm | table | postgres
          public | turn_realm_option    | table | postgres
          public | turn_secret          | table | postgres
          public | turnusers_lt         | table | postgres
     (8 rows)

     coturn=# \d allowed_peer_ip
                               Table "public.allowed_peer_ip"
      Column  |          Type          | Collation | Nullable |  Default ----------+------------------------+-----------+----------+-----------------------      realm    | character varying(127) |           | not null | ''::character varying
      ip_range | character varying(256) |           | not null |
     Indexes:
         "allowed_peer_ip_pkey" PRIMARY KEY, btree (realm, ip_range)

     coturn=# \d denied_peer_ip
                               Table "public.denied_peer_ip"
      Column  |          Type          | Collation | Nullable |  Default ----------+------------------------+-----------+----------+-----------------------      realm    | character varying(127) |           | not null | ''::character varying
      ip_range | character varying(256) |           | not null |
     Indexes:
         "denied_peer_ip_pkey" PRIMARY KEY, btree (realm, ip_range)

     coturn=# \d turn_secret
                                Table "public.turn_secret"
     Column |          Type          | Collation | Nullable |  Default --------+------------------------+-----------+----------+-----------------------      realm  | character varying(127) |           | not null | ''::character varying
      value  | character varying(256) |           | not null |
     Indexes:
         "turn_secret_pkey" PRIMARY KEY, btree (realm, value)

Why it says "probably, the tables 'allowed_peer_ip' and/or 'denied_peer_ip' have to be upgraded to include the realm column" ?

Have no idea, probably need to see if someone answers that in response to your issue:
https://github.com/coturn/coturn/issues/484
Why it says "permission denied" for table turn_secret and for table allowed_peer_ip?

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.


How to solve the problem?
