Interesting! This is one reason why I'm adamant about "deinstalling" all unnecessary modules prior to my upgrade to 11.2. Some necessary ones, too, which I will install manually after the upgrade is complete, even though it looks like this particular issue is accounted for in the upgrade script (if it's "xdbpatch.sql" in 220.127.116.11).
