cnpgvecto.rs

Container images for cloudnative-pg with VectorChord and pgvecto.rs extension installed.

Important

If you are using this image on an existing database, the postgres configuration needs to be altered to enable the extension. You can do this by setting shared_preload_libraries in your Cluster spec:

apiVersion: postgresql.cnpg.io/v1
kind: Cluster
spec:
  (...)
  postgresql:
    shared_preload_libraries:
      - "vectors.so"
      - "vchord.so"

Important

The pgvecto.rs and VectorChord extension is not enabled by default. You need to enable it and set the search path when initializing the database. You can configure it in your Cluster spec:

apiVersion: postgresql.cnpg.io/v1
kind: Cluster
spec:
  (...)
  bootstrap:
    initdb:
      postInitSQL:
        - ALTER SYSTEM SET search_path TO "$user", public, vectors;
        - CREATE EXTENSION IF NOT EXISTS "vectors";
        - CREATE EXTENSION IF NOT EXISTS vchord CASCADE;

Building

To build the Dockerfile locally, you need to pass the CNPG_TAG, PGVECTORS_TAG and VECTORCHORD_TAG args. For example:
docker build . --build-arg="CNPG_TAG=17.5-bookworm" --build-arg="PGVECTORS_TAG=v0.4.0" --build-arg="VECTORCHORD_TAG=0.4.3"
