From e2d156fa6e8a72fe36b956ea12f2eb09c9320792 Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>
Date: Fri, 30 Aug 2002 19:23:20 +0000
Subject: Add attisinherited column to pg_attribute; use it to guard against
 column additions, deletions, and renames that would let a child table get out
 of sync with its parent.  Patch by Alvaro Herrera, with some kibitzing by Tom
 Lane.
