This doesn't generate a unique id. You could back up a standby and restore it and point it at the original master and end up with two standbies with the same id.
If you want to enforce something unique throughout a cluster, I think we're stuck with having the cluster communicate IDs across an entire cluster. AFAIK that's how both Slony and londiste 3 do it. I think it's also noteworthy that Slony and londiste both rely on the user specifying node identifiers. They don't try to be magic about it. I think there's 2 advantages there: - Code is simpler - Users can choose a naming schema that makes sense for them -- Jim C.
