Well _that_ you really don't need multi-volume for. :) You could have
done that with just two independent resources (with 8.3, as well).

Where multi-volume does help you is if you need to keep your PostgreSQL
and MySQL databases in some sort of sync, i.e. you need to enforce write
fidelity across both databases. Which is a bit unlikely, if I may say so.

Cheers,
Florian
