For the record, that's the wrong way round. For the data partitioning

Are you sure?
Yes. :) You actually shouldn't need metadata journaling in either
case--fsck will do the same thing. But fsck can take a *very* long time
on a large paritition, so for your data partition the journaling fs is a
big win. But your wal partition isn't likely to have very many files
and should fsck in a snap, and data consistency is taken care of by
synchronous operations. (Which is the reason you really don't need/want
data journalling.)
