No, the postmaster does not care how badly the stats collector croaks,
because the collector's not connected to shared memory, so there's no
risk of collateral damage.  It'll just start a new one without bothering
the backends.  So you can do whatever you have to do to kill the stuck
collector --- I was just not sure how to do that under Windows.
