Even if others agree and we change this GUC name to "sync_replication_slots", I feel we should keep the values as "on" and "off" currently, where "on" would mean 'sync failover slots' (docs can state that clearly). I do not think we should support sync of "all kinds of supported slots" in the first version. Maybe we can think about it for future versions. thanks Shveta
