This commit has broken CI for me. On the "Windows - Server 2022, VS
2019 - Meson & ninja" build, the following shows up in
046_checkpoint_logical_slot_standby.log:

2026-01-27 13:44:44.421 GMT startup[5172] FATAL:  could not rename
file "backup_label" to "backup_label.old": Permission denied

I imagine this is going to break CI for everybody else too, as well as cfbot.
