I'm aware. What I'm asking is why multi master is required. You can have a read only slave that is promoted to the master. It's that little bit of downtime during failover in question? Doesn't pgpool make that possible without downtime? If you use multi master and DNS failover you still have partial downtime for every session routed to the unhealthy master. That doesn't seem to solve the problem, just a little better.
