From ef590e101ec2e7fd4d2c80b925ce2188aa000bba Mon Sep 17 00:00:00 2001
From: Jan Wieck
Date: Sun, 7 Feb 1999 16:17:14 +0000
Subject: Changed ExecConstraints() and ExecRelCheck() to cache the constraints
 qualification expression trees in the execution state. Prevents from memory
 exhaustion on INSERT, UPDATE or COPY to tables that have CHECK constraints.
 Speedup against the variant using freeObject() is more than factor 2.
