If you trust that your NAS device is reliable enough, then you should be OK. Since I trust that you don't access the PostgreSQL data area concurrently from multiple hosts, you at least won't have any weird cache coherency problems that NFS is known for. -- Peter Eisentraut http://developer.postgresql.org/~petere/
