Does that also explain why the OP could repair some repositories by
simply dumping and loading them? Or would dump+load also work for
corruption-instances that are not on the root node?

seem like a "breaking corruption", since it can be recovered from
quite easily.

If that is not the case, and some unrecoverable instances remain (that
cannot be dumped+loaded), can we offer any other suggestions to
recover?
