pgEdge/control-plane v0.4.0-rc.2 on GitHub

v0.4.0 - 2025-10-06

Introduced stop-instance and start-instance APIs to allow users to manually trigger a stop/start of a specific Postgres instance.
Added support for adding new database nodes with zero downtime.
Added stopped state for instances
Added switchover support via the control plane API
Added a "cancel database task" API endpoint
Added validation to update-database to reject requests that update the database name.
Added support for mTLS to the Control Plane API via user-managed certificates.
Implemented the "get host" and "get cluster" endpoints.
Added Failover support via the control plane API

Switched to the new images from github.com/pgEdge/postgres-images.
Added the postgres minor version to the postgres_version fields in the database and host APIs.
Changed the database creation behavior so that the first host in host_ids gets the primary instance for a node.
Database update process so that nodes are processed one at a time. Within a node, replicas are always updated before the primary.
Added automated switchovers before and after an instance is restarted as part of an update.
Added validation to the update database API to reject requests that update the Postgres major version.
Changed MQTT interface in client library to take an endpoint. This removes the need to generate unique client IDs per server. Callers are responsible for calling Connect() and Disconnect() on the endpoint.
Enable fast basebackup for new nodes. This noticeably speeds up the creation process for a node with replicas.
Changed patroni configuration to use pg_rewind for faster recovery after a switchover.

Fixed join cluster timeouts when requests were submitted to a member other than the raft leader.
Ensure that join and init cluster calls only return once the server is ready to take requests. Any errors during the initialization process will now be returned to callers.
