Right, at this point v17 is not a target of these notes, so I just
documented what happens in <= 16. I did include the commit hashes
for v17/master in the comments, but that's mostly to reassure anyone
who looks that the issue was addressed in those branches.

I think we usually just say VACUUM. If it affected autovacuum
differently, that might be worth documenting; but IIUC it's the
same.
