          You might encounter a PG::CheckViolation error during database migrations, likely due to stale data in the ci database that belongs in the main database, or vice versa. To address this, you can run:

            gdk truncate-legacy-tables
        MESSAGE
      end

      def stale_data_needing_attention?
        GDK::Command::TruncateLegacyTables.new.truncation_needed?
      end
    end
  end
