attached patch provides a configuration in pglb.conf that allows the the load 
balancer to use the IP Address specified in pglb.conf for (out bound) 
connections to PG Backends.

This is a useless configuration for machines with only one local IP Address, 
in which case it is safe to leave the line in pglb.conf commented out or not 
present at all.

This was done against 1.5.0 RC7.
