I think we need to discuss the names of the parameter. Parameter names were also discussed in the above thread. It was suggested to name them 'max_replication_origin_states' or 'max_tracked_replication_origins'. Personally, I find 'max_replication_origin_states' easier to understand, although it is a long name. Best Regards, Keisuke Kuroda NTT Comware
