title: How to use DBUtils in Python 3?
body: <p>I have the following code:</p>
  
  <pre><code>from DBUtils.PooledDB import PooledDB
  import pgdb
  pool = PooledDB(creator=MySQLdb,
              mincached=1,
              maxcached=20,
              host='127.0.0.1',
              port=3306,
              user='root',
              passwd='XXX',
              db='test')
  </code></pre>
  
  <p>but it can't find the <code>MySQLdb</code> module. Is it possible for Python 3 to install MySQLdb? If not, how should can change code to initialize the pool?</p>
