1.0.0

Tested wal telemetry data on replicas
Added waiting query detail info

0.2, Pg 10 support and better replica support

0.2 adds the following features:

• PostgreSQL 10+ is now supported. We conditionally create functions for compatibility as needed in
  the appropriate schema.
• Can now run wal telemetry readings on slaves. Note that tis means something different than it does on the
  master, namely that we are measuring our average awl-reply to the current moment from the time the wal
  telemetry log entry was written on the master.

First release

Generally useful queries. Prometheus exporter configs for prometheus-postgres, and zabbix alerts.
