If using Linux, you may put it under watch with
# auditctl -w /path/to/postmaster.pid -k pgpid
If that records too many events, it can be filtered further, for
example this should catch only deletions:
# auditctl -a exit,always -F path=/path/to/postmaster.pid \
-F arch=b64 -S unlink -S unlinkat -k pgpid
Once in effect, the records about which process/user/command
deletes the file and when would be obtained with:
# ausearch -k pgpid
Best regards,
