----------------------------------------

I see the following alternatives:
1. Fix the original issue
2. Only document the limitation without enforcing it
3. Disallow recovery from non-changelog checkpoints (only allow savepoints as
Dawid mentioned)
{quote}
I presume 3. would be easier to implement compared to the `LEGACY` check we
discussed earlier? And you mean allowing recovery only from changelog
checkpoints or canonical savepoints (native savepoints wouldn't be supported)?
If so I would be also fine with that (especially if we could implement such
check in the changelog package) for the time being until we fix the original
issue.
