I wasn't up to now ;-) The problem here seems to be that the sl_listen is entirely messed up which as a side effect triggers what appears to be a bug. Why rebuildListenEntries() generates 10 entries for a 3 node setup for sure needs some investigation. The real underlying problem is that slon at copy_set() time looks from where it got the event and if that node is not the one providing the data, it checks if it has seen a confirmation of the ENABLE_SUBSCRIPTION from the data provider. The thing here is that data provider is actually the event origin and nodes don't confirm their own events. So the check needs to exclude the case where the event origin is the data provider.
