title: Why psql doing nothing with -h param?
body: <p>I have installed postgres, then I created new user and opened md5 authentication on 127.0.0.1 in pg_hba.conf</p>
  
  <pre><code># "local" is for Unix domain socket connections only
  local   all             all                                     peer
  # IPv4 local connections:
  host    all             all             127.0.0.1/32            md5
  # IPv6 local connections:
  host    all             all             ::1/128                 md5
  </code></pre>
  
  <p>But now if I try to connect via psql with "-h" flag with "127.0.0.1" and this user psql doing nothing.</p>
  
  <pre><code>-bash-4.2$ psql -h 127.0.0.1 -U k4fntr
  </code></pre>
  
  <p>it is just freez</p>
