The service is currently under development.
A C microservice that helps instantly determine the status of your PostgreSQL hosts — including whether they are alive, which one is the master, which ones are replicas, and how far each replica is lagging behind the master.
pg-status polls database hosts in the background at a specified interval and exposes an interface that can be used to retrieve a list of hosts meeting given conditions.
It always serves data directly from memory and responds extremely quickly, so it can be safely used on every request.
