I see the point about combining the three SET commands to reduce round trips, but I think the current approach in the patch (i.e., issuing a separate SET command for each parameter) is sufficient. I still don't think the additional round trip during replication connection startup is a real concern. This approach is also consistent with what postgres_fdw and pg_dump already do.
