Usage

Notes:

You should enable pgvector extension. There is a docker image you can use to play around with it locally:

DO $$ BEGIN
  IF NOT EXISTS (SELECT * FROM pg_extension WHERE extname = 'vector') THEN
    CREATE EXTENSION vector;
  END IF;
END $$;

Docker:

docker-compose build && docker-composer -d up
