I like Postgresql, but it&#x27;s far from superior to MySQL from an ops monitoring point of view. MySQL exposes a lot more information and run-time stats than Postgresql does. Simple things in MySQL are also impossible in Postgresql. How do you simply and effectively guarantee that your Postgresql replicas are not lagged and are indeed connected to the master and successfully writing down new logs in a streaming hot standby replica? You can, but it requires that all of your replication accounts also have superuser access on the master. Fun stuff, that.
