Thanks for commenting.

I may be misunderstanding your words, but as far as I see it the
pg_rusage_init() is only called if we're going to go into recovery.
The pg_rusage_init() and pg_rusage_show() seem to be in the same
scope, so I can't quite see how we could do the pg_rusage_init()
without the pg_rusage_show().  Oh wait, there's the possibility that
if recoveryTargetAction == RECOVERY_TARGET_ACTION_SHUTDOWN that we'll
exit before we report end of recovery.  I'm pretty sure I'm
misunderstanding you though.

If it's easier to explain, please just post a small patch with what you mean.
