... or someone tripping over a power cord to the UPS or someone hitting the
reset button on the machine thinking it was a different machine -- the thing
is that with fsync() off, even someone hitting the reset button on the
machine and rebooting it could cause severe database corruption even though
the rest of your system is virtually unharmed with a spontaneous reboot
(minus the running of fsck or other utilities to verify the drive's
integrity )..

I agree that the chances of it happening are probably low but if the data is
mission critical then I wouldn't even take a small chance with corruption..

Just be careful!
