So ... none of the Windows buildfarm members actually like this
test script. They're all showing failures along the lines of
not ok 2 - fails if basebackup_to_shell.command is not set: matches
# Failed test 'fails if basebackup_to_shell.command is not set: matches'
# at t/001_basic.pl line 38.
# 'pg_basebackup: error: connection to server at "127.0.0.1", port 55358 failed: FATAL: SSPI
authenticationfailed for user "backupuser"
# '
# doesn't match '(?^:shell command for backup is not configured)'
Does the CI setup not account for this issue?
