Announcing the release of pg_cirrus v2.0: Automating Production-Grade Postgres HA Clusters

Stormatics is excited to announce the release of pg_cirrus v2.0, bringing major improvements to high availability cluster automation for Postgres. pg_cirrus was developed to help you automate the deployment of a 3-node Postgres cluster via Pgpool and save time required to set up a cluster manually while ensuring reliability. This release builds on feedback from real-world deployments and delivers greater resilience, faster setup, and improved operational visibility, ready for production.

###Highlights of the release

####1. True High Availability with Watchdog-Enabled Clusters
Deploy a three-node PostgreSQL cluster with Pgpool running on all nodes, removing the single point of failure present in previous setups.
With pg_cirrus v2.0, if one Pgpool node goes down, the cluster continues to operate seamlessly, ensuring uninterrupted service.

####2. Service-Enabled Docker Container Support
You can run pg_cirrus inside lightweight, minimal-size service-enabled Docker containers for much faster deployments than full OS installations. Service integration allows for simple start/stop management, making it easier to operate in containerized environments.

####3. Enhanced Logging for Easier Troubleshooting
Improved pg_cirrus logging capabilities provide richer insights into deployment steps, making it easier to monitor and troubleshoot the cluster during deployment.

###Supported PostgreSQL Versions
PostgreSQL 17, 16, 15, 14, and 13
