    Hi there.
    Using the 'sudo -u postgres psql' command I created a group and
      two accounts in the group, I also created a database for one of
      the accounts. Now, I'd like to login PG-15, using my new account
      and connecting to my new database, but PG-15 complains. See the
      example below, I think it is clear than my English.

    
    CREATE ROLE my_group; // Create a group

      CREATE ROLE my_group_admin LOGIN PASSWORD 'AdminPassword'
        CREATEDB CREATEROLE; // Create admin

      CREATE ROLE my_group_worker LOGIN PASSWORD 'WorkerPassword'
        CREATEDB; // Create Worker

      GRANT my_group TO my_group_admin WITH INHERIT TRUE;

      GRANT my_group TO my_group_worker WITH INHERIT TRUE;

      
      CREATE DATABASE my_group_db WITH OWNER my_group_worker;

      \q

      psql -U my_group_worker -d my_group_db
    psql: error: connection to server on socket
        "/var/run/postgresql/.s.PGSQL.5432" failed: FATAL:  Peer
        authentication failed for user "my_group_worker"
    *** What am I doing wrong?
    

    Thanks in advance.
