Multiple backends on a single physical database

I am wondering if it is sane to mount PGDATA over NFS on many
machines and run posmaster backends on them, so that all the
postmasters are using the same database.

Obviously performance is going to suffer because network traffic
is going to be high, but later we may use a distributed filesystem
with replications instead of NFS.

Thanks in advance.
