Hmm, someone may have to correct me on this but last time I checked all
the
journalling filesystems currently available journalled *filesystem*
*metadata*. IOW, after a crash, the filesystem structure will be intact,
but your database maybe completely corrupt.

Anyway, how does the filesystem driver know what is a consistant state
for the database? For that postgres would have to do it's own
journalling,
right?
