title: dynamic database and dict cursor in MySQLConnectionPool
body: <p>I have been trying to use connection pool for mysql in python. While searching for options, I came across <code>MySQLConnectionPool</code>. It seems to work decently but I am not able to find how to achieve some of the features of MySQL.</p>
  
  <ol>
  <li>How to dynamically select database. </li>
  <li>How to use dict_cursor. For
  normal MySQL without pool, I use
  <code>cursorclass=MySQLdb.cursors.DictCursor</code></li>
  </ol>
  
  <p>If someone knows about how to achieve this, please let me know. Thanks in advance.</p>
