You are aware that that's widely considered either useless or
counterproductive? Renice-ing one backend seldom gives helpful results,
because (a) what usually matters more than CPU usage is I/O, and renice
doesn't change I/O priorities; (b) priority inversion results in
higher-priority backends blocking behind the low-priority one whenever
it's managed to acquire a lock.
