… tables See the issue for more commentary on the problem. In short, we never dropped offline tables during `DROP DATABASE ... CASCADE` which would end up leaving those tables completely orphaned. Orphaned tables with no parent are a problem. Perhaps it would be better to stop the relevant jobs and then clean up after them but that's a much more involved fix. Fixes cockroachdb#48589. Release note (bug fix): Prevent dropping of databases which contain tables which are currently offline due to `IMPORT` or `RESTORE`. Previously dropping a database in this state could lead to a corrupted schema which prevented running backups.
