I think this highlights exactly what I'm trying to emphasise: in actual, shared-nothing systems like this, there's no possible guarantee of "never". There are possible guarantees of "very rarely". The problem is, you're already trying to address a teeny portion of the likely events on your machines. So you have to assume that more than one thing might break at the same time, and have a recovery plan for it. I submit that a recovery plan of "restore from pg_dump" is usually not going to be enough if it was worth the cost and hassle of setting up shared disk failover. YMMV, of course.
