This repository contains a custom Docker image based on cloudnative-vectorchord with the pgvecto.rs extension pre-installed. It is designed to support a safe and smooth migration from pgvecto.rs to VectorChord for projects such as Immich using cloudnative-pg to manage their PostgreSQL clusters.

Starting from Immich v1.133.0, the pgvecto.rs extension is deprecated in favour of VectorChord, offering better performance and more stability.

However, in order to migrate existing databases, both extensions (pgvecto.rs and VectorChord) must be available at the same time in the PostgreSQL image. This image makes that possible.

• 🐘 Base: ghcr.io/tensorchord/cloudnative-vectorchord:16-0.3.0
• ➕ Adds pgvecto.rs v0.2.0 (as a .deb package)
• ✅ Compatible with cloudnative-pg
• ✅ Tested with Immich v1.133.0+

spec:
  image:
    name: ghcr.io/corentingiraud/cnpg-pgvector-vectorchord
    tag: 16-migration

• Only use this image during the migration phase.

• Once your migration is complete and Immich works correctly, you can switch to a leaner image with just VectorChord, like:

  ghcr.io/tensorchord/cloudnative-vectorchord:16-0.3.0
  

• pgvecto.rs
• VectorChord
• Immich
• cloudnative-pg
