title: PSql: how to not remove comments for external editor?
body: <p>I like to use <code>psql</code>, and sometimes I commenting part of query (usually one line) - something like "quick fix and see what you get".</p>
  
  <p>Internal <code>psql</code> editor is not suitable for big queries, and so often I'm using external editor via <code>\e</code> (currently it's <code>vim</code>).</p>
  
  <p>The problem is when some part of query is currently commented in <code>psql</code>, then it appearing as empty line in external editor.</p>
  
  <p>How I can configure <code>psql</code> to not remove comments when external editor is called?</p>
