title: PostgreSQL: Convert timestamp to time - or retrieve only time from timestamp column
body: <p>What I want is something equivalent to this:</p>
  
  <pre><code>select to_time( to_timestamp ( '03.04.2014 12:34:00', 'DD.MM.YYYY HH24:MI:SS' ) )
  </code></pre>
  
  <p>Problem here is that to_time does not exist. I want this to result in</p>
  
  <pre><code>12:34:00 (without the date)
  </code></pre>
  
  <p>Is this possible ?</p>
