Isn't it better to give a Notice when force_alter option leads to the
rollback of already prepared transactions?

I have another question on the latest 0001 patch:
+ /*
+ * Stop all the subscription workers, just in case.
+ * Workers may still survive even if the subscription is
+ * disabled.
+ */
+ logicalrep_workers_stop(subid);

In which case the workers will survive when the subscription is disabled?
