From 88b17d9c56bfd0b6d35b824e9edbce29ae241c33 Mon Sep 17 00:00:00 2001
From: "Marc G. Fournier" <scrappy@hub.org>
Date: Tue, 25 Aug 1998 21:24:12 +0000
Subject: [PATCH] From: Massimo Dal Zotto <dz@cs.unitn.it>
> ps-status.patch
>
> macros for ps status, used by postgres.c and utility.c.
> Unfortunately ps status is system dependent and the current
> code doesn't work on linux. The use of macros confines system
> dependency to into one file (ps-status.h). Users of other
> operating systems should check this code and submit new macros.
