From 5f74d499bfc07c43f44d0989aab6b23c6b5bfbb0 Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>
Date: Thu, 17 Jun 1999 22:21:41 +0000
Subject: Defend against function calls with more than 8 arguments (code used
 to overrun its fixed-size arrays before detecting error; not cool). Also,
 replace uses of magic constant '8' with 'MAXFARGS'.
