title: Propel schema.xml generation without columns from postgres
body: <p>I am trying to generate a postgres database schema. For example, I made a new table called awesome, with pk and one more column, both varchar(50).</p>
  
  <p>When using postgres reverse, I get this result (missing pk, columns):</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;database name="default" defaultIdMethod="native" defaultPhpNamingMethod="underscore"&gt;
    &lt;table name="awesome" idMethod="native" phpName="Awesome"/&gt;
  &lt;/database&gt;
  </code></pre>
