I'd be fairly surprised if resetting the variable in the child process
had any effect on the postmaster...
I think a correct fix would involve exposing either the variable or a
routine to zero it from pgstat.c, and having postmaster.c do that at
the points where it intentionally SIGQUITs the stats collector.
