Good point. The OP said "all databases" but that may actually not be
what they need.
In fact, having tablespaces spread across both drives should give them
some performance benefits (xlog on original drive, big tables on other
drive) ... though it *does* expose them to losing the entire cluster if
EITHER drive fails. Good backups become even more essential.
