This makes sense to me. I think we can avoid reserving 'local' for now
till we agree on its use case and implementation. One similar point
about slots is that we treat 'none' slot_name in subscription commands
as a special value indicating no slot name whereas we do allow
creating a slot with the name 'none' with
pg_create_logical_replication_slot(). So, if we want to follow a
similar convention here, we may not need to add any restriction for
origin names but personally, I think it is better to add such a
restriction to avoid confusion and in fact, as a separate patch we
should even disallow creating slot name as 'none'.
