Singapore – August 18, 2025

We are excited to announce the release of pg_cirrus v2.0, bringing major improvements to high availability cluster automation for Postgres. pg_cirrus, an open-source tool by Stormatics, 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. This release builds on feedback from real-world deployments and delivers greater resilience, faster setup, and improved operational visibility, ready for production.

Highlights of this release include:

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.
  

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.
  

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
  

Supported Platforms

• Ubuntu 22.04 and 24.04
• Red Hat Enterprise Linux 9
