You didn't provide enough information. Linux distro and version?

I would say that the operating system is the one that is probably removing the 
postmaster.pid. You are using /tmp as your base directory. Service like
systemd-tmpfiles-clean removes temporary files from /tmp. If systemd is not in
use, I would check the cron.

Base docker images were:
-  docker.io/library/alt:p10 (it is altlinux 10)
-  docker.io/library/postgres:17-alpine (alpine linux)
