If you already have a frontend proxy, you shouldn't have a lot of idle servers holding db connections. Assuming that your application uses the database on every mod_perl request, only processes that are actually sleeping will not be using their connection.
you can also look for db proxies/pools i use/used pgpool , because i only use pg i tested out sqlrelay a while back on mysql, and it seemed great http://sqlrelay.sourceforge.net/
