I think it will be good to set replorigin_session_origin_timestamp = 0 explicitly so as not to pick up a garbage value. The timestamp is written to the commit record. Beyond that I don't see any use of it. It is further passed downstream if there is cascaded logical replication setup. But I don't see it being used. So it should be fine to leave it 0. I don't think we can use logically replicated sequences in a mult-master environment where the timestamp may be used to resolve conflict. Such a setup will require a distributed sequence management which can not be achieved by logical replication alone. In short, I didn't find any hazard in leaving the replorigin_session_origin_timestamp as 0. -- Best Wishes, Ashutosh Bapat
