Commit 428b260f8 broke planning of cases where row marks are needed (SELECT FOR UPDATE, etc) and one of the query's tables is a foreign table that has regular table(s) as inheritance children. We got the reverse case right, but apparently were thinking that foreign tables couldn't be inheritance parents. Not so; so we need to be able to add a CTID junk column while adding a new child, not only a wholerow junk column. Back-patch to v12 where the faulty code came in.
