I think it is, if I've understood your requirements correctly. e.g. from the datasette-faiss docs:

  with related as (
    select value from json_each(
      faiss_search(
        'intranet',
        'embeddings',
        (select embedding from embeddings where id = :id),
        5
      )
    )
  )
  select id, title from articles, related
  where id = value

Really? Have you actually tried this? In my experience Heroku couldn't make it any easier. You can provision a database in 60 seconds, from a Deploy to Heroku button in your Github README, or in the lovely dashboard, or on the CLI, or with two lines in heroku.yml.

We're a heavy Gitlab user and I'm a big fan of Gitlab's typically transparent communications style, but this article reflects really badly on you. I think you should take it down.
