I see your point. But it would allow you to use a relatively modest 
local partition for WAL segments, while you might be using a 1TB netapp 
tray over NFS for the archive segments. I guess if the archive partition 
fills up, I would err on the side of dropping archive segments on the 
floor. That would mean a new full backup would be needed, but at least 
it wouldn't result in a corrupt, or shut down, database.
