I dunno, it seems like this may be common knowledge for Windows people
and I was just being paranoid by asking for more info as a
non-Windowsian, but if you want to propose new comments or perhaps
just a pointer to one central place where we explain how that works, I
wouldn't be against that.

FWIW I just spotted a couple of very suspicious looking failures for
build farm animal "walleye", a "MinGW64 8.1.0" system, that say:

c:\\pgbuildfarm\\pgbuildroot\\HEAD\\pgsql.build\\src\\bin\\pg_upgrade>RMDIR
/s/q "c:\\pgbuildfarm\\pgbuildroot\\HEAD\\pgsql.build\\src\\bin\\pg_upgrade\\tmp_check\\data.old"
The directory is not empty.

Then I noticed it failed the same way 8 days ago, so I don't know
what's up with that but it looks like we didn't break it...
