Oh, it looks like this new build farm animal "skimmer" might be
reminding us about this issue:

https://buildfarm.postgresql.org/cgi-bin/show_history.pl?nm=skimmer&br=HEAD

I don't know why it changed, but since this is an LSN/page alignment
thing, it could be due to external things like an OS upgrade adding
more locales or something that affects initdb. Will look soon and
fix.
