I do agree with you that we should not play games with postmaster. Better to be safe than sorry. (So, manually deleting pid file is the only safe option). I was just suggestion (possibly dangerous) workaround. Btw, I do check for running postmaster, using full path (I don't wan to kill every postmaster on the system), is this safe? Or there could be race condition?
