From 0a95a17da2b7b9e34ecaeefa9f910c04977b277e Mon Sep 17 00:00:00 2001
From: "Thomas G. Lockhart" <lockhart@fourpalms.org>
Date: Sun, 27 Apr 1997 19:24:16 +0000
Subject: [PATCH] Change mixed-case routines to lower-case for case-insensitive
 SQL. Add mixed-case #define synonyms to avoid changing more source code. Add
 comparison operators for boolean. Add aggregate min() and max() for datetime
 and timespan.
