title: hibernate does not reconnect once the database is bounced
body: <p>I've found that after we've bounced (stopped and started) our database (postgresql 8.3), our apps which use hibernate (3.2.6) fail to re-acquire connections, instead getting a SocketException with the message "broken pipe".</p>
  
  <p>I believe we're configured to use the built in connection pooling.</p>
  
  <p>how can i make hibernate re-acquire connections after a db restart without restarting the app?</p>
