title: PostgreSQL ORDER BY column position (and not by column name)
body: <p>Basically, I don't want:</p>
  
  <p><code>SELECT firstname, lastname FROM person ORDER BY lastname;</code></p>
  
  <p>But rather:</p>
  
  <p><code>SELECT firstname, lastname FROM person ORDER BY &lt;column number 2&gt;;</code></p>
  
  <p>I could create a mapping but I was wondering if there is a native trick to do it.</p>
