It failed like:
https://api.cirrus-ci.com/v1/artifact/task/5709014662119424/testrun/build/testrun/pg_upgrade/002_pg_upgrade/log/regress_log_002_pg_upgrade
[19:35:31.017](76.307s) ok 10 - run of pg_upgrade for new instance
[19:35:31.017](0.000s) not ok 11 - pg_upgrade_output.d/ removed after pg_upgrade success
[19:35:31.018](0.001s) # Failed test 'pg_upgrade_output.d/ removed after pg_upgrade success'
# at C:/cirrus/src/bin/pg_upgrade/t/002_pg_upgrade.pl line 261.

This is a transient failure; it normally passes:
https://cirrus-ci.com/github/postgresql-cfbot/postgresql/commitfest/39/3389

Actually, it's the same problem as reported here:
20220919213217(dot)ptqfdlcc5idk5xup(at)awork3(dot)anarazel(dot)de

I don't think there's anything in place to help scrape the cirrusci
logs, but I suppose other patches have had/will have this same failure.

I don't know but maybe meson made this worse, by exercising/stressing
concurrent filesystem operations.
