The Automatic failover is already available, we use the RH cluster
solution and it works really well, we never had a failure till now
but all the our simulations ( power off, hardware failure ) are
working well. We have almost 3 year of 24/24 7/7 without macro
interruption, only fews minutes during the 7.0 -> 7.1 -> ... -> 7.4
upgrades. With the RH solution we are also able to perform the
minor upgrades ( 7.4.1 -> 7.4.2 for example ) without one single
minute of interruption:
1) Upgrade on passive node2) Relocation service 3) Upgrade on the active node4) Relocation service
it would be great from this point of view if the pg_upgrade could handle
also the major version upgrade without need to dump, init, reload the db.
