There may be some platform dependency involved --- in particular, you
wouldn't see the issue unless one keystream has two nonlossy TIDs on the
same page as the other one has a lossy TID, so it's going to depend on
the placement of heap rows. Anyway, I can reproduce it just by loading
the given dump, on both 8.4 and HEAD. Will work on a fix.
