From 4d567013cf127d10acb5da01c4a484bb635eebe8 Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>
Date: Sat, 25 May 2002 20:00:12 +0000
Subject: Remove AMI_OVERRIDE tests from tqual.c routines; they aren't
 necessary and just slow down normal operations (only fractionally, but a
 cycle saved is a cycle earned).  Improve documentation of AMI_OVERRIDE
 behavior.
