title: Show query result column types (PostgreSQL)
body: <p>Is there a way to easily get the column types of a query result?  I read the psql documentation, but I don't think it supports that.  Ideally, I'd be able to get something like:</p>
  
  <pre><code> columna : text | columnb : integer
  ----------------+-------------------
   oh hai         |                42
  </code></pre>
  
  <p>Is there a way I can get this information without coding something up?</p>
