I want to load balance a postgres server on 4 physical machines, say  I can set up a pgbouncer on and connection pooling to my four boxes.  However, the traffic from/to clients will go through an extra hop.  Another way to do this, is to send the client an "redirect" message.  When client connect to, instead of accepting the connection, it can reply to client telling it to reconnect to one of the server on  

I am planning to write/submit a patch to do that.  I wonder if there is similar effort in extending libpq protocol, or, if you have better ideas on how to achieve this.

Thank you,
