from man postgres:
-F Disable an automatic fsync() call after each trans
action. This option improves performance, but an
operating system crash while a transaction is in
progress may cause the loss of the most recently
entered data. Without the fsync() call the data is
buffered by the operating system, and written to
disk sometime later.
