Recovering stat file from crash

Hi,

I created a .patch that will allow me to recover the stat files after a
potential crash.
Depending on the traffic on the server some records might be lost (0.5 sec
of records / more or less ? ).
From what I read it is still better than no stat files at all.

I restricted it to the default recovery scenario only
(RECOVERY_TARGET_TIMELINE_LATEST) to avoid having invalid stats files with
other recovery options.

Am I missing something ? File integrity should be fine because of renaming.
