I haven't read this thread in detail, but I have one high-level design question. The upgrade of the replication slot is default or is it under some GUC? because if it is by default then some of the users might experience failure in some cases e.g. a) wal_level in the new cluster is not logical b) If this new check check_old_cluster_for_confirmed_flush_lsn() fails due to confirm flush LSN is not at the latest shutdown checkpoint. I am not sure whether this is a problem or could be just handled by documenting this behavior. -- Regards, Dilip Kumar EnterpriseDB: http://www.enterprisedb.com
