Not really, I thought an ack on a commit would mean that the data
is actually in stable storage, breaking that would be pretty bad
no? Or are you only talking about when someone is running with
async Postgresql?
Although this doesn't have an effect on my current application,
when running Postgresql with sync commits and WAL can one expect
the old behavior, ie. success only after data and meta data (log)
are written?
Another question I had was what would the effect of a mid-fsync
crash have on a system using WAL, let's say someone yanks the
power while the OS in the midst of fsync, will all be ok?
