Well, you could NFS-mount the remote directory and have it work that
way.  One complexity is that you need to start/stop the old and new
servers, so doing something without NFS is going to be vary hard.

I think it is much simpler to just copy the old clsuter to the remote
server and run pg_upgrade in --link mode on the remote server.
