In software I have developed separately, I have noticed that most systems will periodically delete files within the
temporarydirectory hierarchy that have not been accessed recently, and that includes lock files for long running
processes.I have never noticed the lock file associated with a postgreSQL socket be missing though.
Does PostgreSQL periodically touch the lock file so it won’t be deleted? Alternatively, does PostgreSQL simply
re-createthe lock file if it has been deleted? I know the documentation says to never “manually”’delete one of those
lockfiles.
