title: Connection issue with postgres and pg8000 python - clear password issue?
body: <p>I'm trying to connect using:</p>
  
  <pre><code>conn = DBAPI.connect(host='sql2', user='XXX', password='XX', database='XX', socket_timeout=100, port=100)
  </code></pre>
  
  <p>I now find I get the following error:</p>
  
  <pre><code>pg8000.errors.InterfaceError: Authentication method 3 not supported by pg8000.
  </code></pre>
  
  <p>Looking around I get what this may mean:</p>
  
  <pre><code> 3 = Cleartext pwd (not supported by pg8000)
  </code></pre>
  
  <p>Are there any suggestions here?</p>
