Re: [HACKERS] pid file for postmaster?

Red Hat ALREADY creates a file "postmaster.pid" in the /var/lock directory.
I don't know how far the /var/lock convention goes across different platforms,
but I recommend using IT or its equivalent, I still have scars from my OS/2
days where every product put its goodies in a different place and you had to
guess where, how, and in what format.
