probably you are interested in the hot standby feature which is
looking like a lock for 8.5. it's not exactly what you asked for (you
need two complete copies of your database), but you get high
availability, a queryable slave, and very strong data guarantees if
combined with synchronous replication.
As for NAS, just pretend it stands for: Nightmare (of) Administrator
Scenario :-)
