What do you want to guard against? Hardware outage? Software bugs? I don't think that the scenario you describe is possible. There are other, maybe better ways: 1) Have the database on NAS and use storage mirroring. NAS in that case means NFS (hard mount!), *not CIFS*. That will help against hardware outage, but not against filesystem or database corruption. 2) Use a standby database with streaming replication. That will also help with filesystem and database corruption.
