    You must configure your PostgreSQL server before using pgBadger.
    Edit postgresql.conf (in #{var}/postgres if you use Homebrew's
    PostgreSQL), set the following parameters, and restart PostgreSQL:

      log_destination = 'stderr'
      log_line_prefix = '%t [%p]: [%l-1] user=%u,db=%d '
      log_statement = 'none'
      log_duration = off
      log_min_duration_statement = 0
      log_checkpoints = on
      log_connections = on
      log_disconnections = on
      log_lock_waits = on
      log_temp_files = 0
      lc_messages = 'C'
    EOS
  end
