Every time I look into tools like this they are quite far behind for example AlwaysOn in MSSQL. For example, with PG I have to reseed the original master if it comes back online after an outage. It's as far as I can tell not fully automatic and transparent to me as the guy responsible for managing it. With SQL and elasticsearch+ZooKeeper for example nodes can go up and down without anyone noticing it and me not having to do anything. Is this still a place where PG is behind?
