Ah yeah, that sounds about what I was thinking.  I've merged that in and
pushed to github, which had a strange pg_upgrade failure on Windows
mentioning log files that were not captured by the CI tooling.  So I
pushed another one trying to grab those files, in case it wasn't an
one-off failure.  It's running now:

If all goes well with this run, I'll get this 0001 pushed.
