I request to leave this alone for now. I have enough things to juggle with in the NOTNULLs patch; this patchset looks like it will cause me messy merge conflicts. 0004 for instance looks problematic, as does 0007 and 0016. FWIW for the most part that patch is working and I intend to re-submit shortly, but the relevant pg_upgrade code is really brittle, so it's taken me much more than I expected to get it in good shape for all cases.
