If you don't configure delegate_IP, you need to configure your application to
connect to either pgpool.

If you don't configure delegate_IP, you need to modify your application
when the pgpool node is down which is specified in your appication.
The benefit of using delegate_IP is that you don't need to
modify your application source code every time the pgpool master is switched over.
