I think if we want to prevent the creation of subscriptions that point to self, then we need to create a magic token when the postmaster starts and check for that when we connect. So more of a running-instance identifier instead of a instance-on-disk identifier. The other option is that we just allow it and make it more robust.
I think we should go with the second option for now. I feel that the effort is better spent making sure that initial syncs that have don't subscribe (for whatever reasons) can be aborted instead of trying to build a concept of node identity before we really need it.
