drongo just did it too, and it seems repeatable on dory. I'm not 100%
sure, but I think the buildfarm's initial "check" step may be run under C
locale while pg_upgrade sees whatever the machine's prevailing locale is.
If that's correct, it seems like the simplest explanation is just that
extraction of a collation version is busted for (some?) non-C locales on
Windows. Could be something as dumb as spaces in the locale name
being problematic.
