On 14th of December 2025, Alexander Korotkov committed patch: Implement ALTER TABLE ...

We talked to Matthew Mols, Sr. Director of Engineering at pgEdge, about how CloudNativePG enables them to meet the requirements of their customers using just open source.

2025 marked a historic turning point for CloudNativePG, headlined by its acceptance into the CNCF sandbox and a subsequent application for incubation. Throughout the year, the project transitioned from a high-performance operator to a strategic architectural partner within the cloud-native ecosystem, collaborating with projects like Cilium and Keycloak. Key milestones included the co-development of the extension_control_path feature for PostgreSQL 18, revolutionising extension management via OCI images, and the General Availability of the Barman Cloud Plugin.
