By Unset, I mean to say when the configuration parameter 'external_pid_file' is disabled (#external_pid_file). But if the path/filename is changed to different name across restart of server, it will not be able to delete the previous file. So it will not workout the way I was trying to think. However if it is deleted at proc_exit as suggested by Peter, there will be no problem. The reason why I have thought the file not to get deleted at every proc_exit, is a. Initially I thought it might be un-necessary to delete and re-create the file at server shutdown and start. b. I was not sure if this file has usage only till server is running.
