And this actually seems like a likely source of these errors. Removing
a backup label unfortunately causes hard to diagnose errors, because
everything appears to be ok as long as there's no checkpoints while
taking the base backups (or when the control file was copied early
enough). But as soon as a second checkpoint happens before the control
file is copied...
Fredrik, how did you end up removing the label?
