pg-status: microservice for checking the status of PostgreSQL hosts

Hi all!

I'd like to share a small open=E2=80=91sour= ce project I've been working on: pg-status.

pg-status is a lightweight microservice (si= decar) that helps you instantly determine the status of your PostgreSQL hos= ts: whether they are alive, which one is the master, which ones are replica= s, and how far each replica is lagging behind the master.

It's designed to run alongside your main ap= plication. It's lightweight, resource=E2=80=91efficient, and delivers high = performance. You can query it on every request without noticeable overhead.=

pg-status polls your database hosts in the = background at a configurable interval and exposes an HTTP interface that yo= u can use to retrieve hosts matching given conditions.

I originally built it to speed up master de= tection in a multi=E2=80=91host setup where DNS failover was too slow, but = it's also handy for proxy setups or custom load=E2=80=91balancing logic.

Feedback and discussion are very welcome. I= 'd love to hear your thoughts!

Best regards,
Andrei Krylosov
