VSHN AppCat Update – CloudNativePG Becomes the New Default PostgreSQL

The latest VSHN AppCat release v4.187.0 continues the platform’s transition toward a more Kubernetes-native PostgreSQL experience.

With this release, CloudNativePG officially becomes the default PostgreSQL implementation for all newly created PostgreSQL instances in AppCat. Existing instances remain unchanged, but new deployments will automatically use the CloudNativePG-based setup going forward.

This marks another important milestone in the maturation of PostgreSQL operations within AppCat.

CloudNativePG Now Default for PostgreSQL

CloudNativePG has steadily evolved within AppCat over the past releases and has now reached the point where it becomes the standard choice for new PostgreSQL deployments.

For users, this means:

• New PostgreSQL instances automatically use CloudNativePG
• Improved Kubernetes-native operations
• Better long-term maintainability
• Continued investment into the CloudNativePG ecosystem

Teams already running older PostgreSQL implementations can continue operating them normally, while migration planning can happen on their own timeline.

Improvements Across the Platform

Besides the PostgreSQL transition, the release also contains several operational improvements and fixes across the platform.

Better Garage CRD Version Handling

The release improves how Garage CRD versions are handled internally. This helps ensure more predictable behavior during upgrades and platform maintenance.

Improved topologyKey Handling for CloudNativePG

Topology handling for CloudNativePG deployments has been refined to improve scheduling consistency in Kubernetes clusters.

Better Warnings for enableSSHInRelease

The enableSSHInRelease handling now provides improved warning behavior, helping users better understand potential implications during deployments and maintenance operations.

Continuous Improvements Behind the Scenes

Many AppCat releases focus on operational excellence rather than flashy user-facing features – and that’s exactly what keeps production platforms reliable over time.

By making CloudNativePG the default PostgreSQL foundation and continuously refining platform behavior, AppCat keeps moving toward a more stable, Kubernetes-native and future-proof application platform.
