Singapore – August 31, 2023

We are pleased to announce the 1.0-rc1 release of pg_cirrus. This automated tool streamlines the process of setting up a 3-node cluster, making it significantly easier for users to set up and manage high availability in PostgreSQL.

We understand that configuring a PostgreSQL cluster can be a complex and time-consuming task, which is why we have designed pg_cirrus to help make the process faster and more efficient.

Key improvements

• The third cluster node remains responsive even after a second failover.
• Proper load balancing is now ensured after a failover event.
• pg_cirrus now operates under the postgres user rather than the root user.
• Enhanced security: Nodes within the same subnet can no longer connect to the cluster nodes without providing the correct password.
• Compatibility extended to ports other than the default 5432.
• Successful failover execution when pg_cirrus is initiated from the postgres user.
• Updated variable names for clarity.
• Added the vault.yml.in template file.
• Improved exception handling for ansible playbooks; pg_cirrus stops gracefully if a playbook fails.
• Enhanced exception handling for user inputs.

To help you get started with pg_cirrus, we have provided the following resources:
