I'm pretty certain it just assumes your only specifying a DB partition if it's faster than the data and only specifying the WAL partition if it's faster than the data and DB.  It just trusts that your doing it right.

The WAL will choose the fastest device available.

Any idea how it makes this determination automatically? is it doing a hdparm -t or similar? is fastest=bandwidth, IOPs or latency?
