What you see here is a defensive "can't happen" error that I added in
commit 8f72bbac, and backpatched to Postgres 13.4, which came out on
2021-08-12. The goal of that error is to make a possible hard crash
due to corruption into a slightly friendlier kind of failure (the
error that you see here). Were you running 13.4 before the upgrade?
If you were on 13.3 or earlier before the upgrade to 14, then it's
possible that the problem was there all along, but is only now visible
for the first time.
