The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/10/pgupgrade.html Description:
If we use the following command to upgrade the standby server, then new cluster will create by old_cluster which is not correct. rsync --archive --delete --hard-links --size-only --no-inc-recursive old_cluster new_cluster remote_dir I used following command and this one is correct: rsync --archive --delete --hard-links --size-only --no-inc-recursive new_cluster old_cluster remote_dir So the only thing need to change is the place of old_cluster and new_cluster in rsync command.
