From bf1e2d2db5104ce8b764f62f8a742b3fcc66e8a5 Mon Sep 17 00:00:00 2001 From: =?utf8?q?=C3=81lvaro=20Herrera?= Date: Tue, 4 Mar 2025 20:07:30 +0100 Subject: [PATCH] Fix ALTER TABLE error message This bogus error message was introduced in 2013 by commit f177cbfe676d, because of misunderstanding the processCASbits() API; at the time, no test cases were added that would be affected by this change. Only in ca87c415e2fc was one added (along with a couple of typos), with an XXX note that the error message was bogus. Fix the whole, add some test cases. Backpatch all the way back.
