You think that this feature is a high-priority TODO item? We are planning to use the HotStandby feature too. That would require to have the correct state information since we have to control the DB clients when and how they can connect or reconnect. But also in general, from our platform POV it's an important feature to have the right view on the system at any point of time (e.g. in case of update avoid switchover if standby is out of sync, ...). In addition, can we expect that a replication break will be logged as an important event ?
