v1.0

Release Notes

With the v1.0 release of pg_cirrus, we introduce the following features/bug fixes

• 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.
• The failover and follow_primary commands now execute seamlessly when pg_cirrus is executed using the service command and users can view pgpool logs saved in /var/log/pgpool_logs directory.
