I'm not sure, I guess it could work, but NFS is a pretty poor file 
system. There are always issues with file locking across various 
platforms. I recall reading about mmap issues across NFS a while ago 
(forget the platform, sorry). Depending on the NFS server, there may be 
problems there. The NFS client may also have isses with locking, fsync, 
and mmap.

If possible, look for a network block device protocol. The file level 
NFS is probably inadequate for PostgreSQL.
