Well, we point our "stats_temp_directory" to a tmpfs partition, which is probably fairly common (or so I'd guess).
But a full tablespace with tables and everything? That sounds pretty risky for anything other than a place to store
data for transformation or summary of data that could be recreated by restarting a process if the server goes down
in the middle.
I think you'd be better off explaining what your goal is and then people could give you better comments.
HTH,
