There are situations where it's ok, when all the data are
reproduceable from other sources, etc. for instance I have a
reporting server that is a slony slave that runs with fsync off. If
it does crash and I can recreate the node in an hour or so and be back
online. With fsync off the machine is too slow to do its job, and
it's not the primary repo of the real data, so it's ok there.
