That won't fix anything released already, so as per the information
gathered something has to be done anyway. The discussion of this thread
is spreading quite a lot actually.
Handling things at a low-level looks like a better plan for the backend.
Tools like pg_basebackup and pg_dump also issue fsync's on the data
created, we should do an equivalent for them, with some exit() calls in
file_utils.c. As of now failures are logged to stderr but not
considered fatal.
