Thanks for your advice, Erick. I think you point out what I didn't think of and a possible side effect in the future. I'll go back to the "normal" way next time I do the same job.

Well, that'll work, but you better know _exactly_ what you're doing. For instance, you better not be indexing and have committed before you start your copy. You better make sure your third node is up before you index anything. Etc. Etc. Why do you think this "saves time"? Have you measured? Is the time savings worth the risk? Because using ADDREPLICA handles all the edge cases for you and essentially does what you're talking about behind the scenes. And will work even if you're actively indexing. Manually copying things seems to be adding additional places for you to get it wrong for a pretty rare operation, I'd bet that the time you spend manually creating a replica could be better spent letting the ADDREPLICA run in the background while you do other more important things.
