Possibly related: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=934068 (I'm not sure if that start-stop-daemon issue is merely cosmetic or the actual cause of this problem, and the upstream issue doesn't say).

This is still a problem in 19.10.

The patch from https://bugs.debian.org/cgi-bin/bugreport.cgi?att=1;bug=934068;filename=postgrey_init.patch;msg= fixes the reload problem.

[Marius Gedminas (mgedmin)]

Still a problem in 20.04 LTS.
