    A specialized translator designed to work with Supabase, extending the BaseTranslator class. It translates structured queries into a format that can be understood by the Supabase database.

    const selfQueryRetriever = new SelfQueryRetriever({
      llm: new ChatOpenAI({ model: "gpt-4o-mini" }),
      vectorStore: new SupabaseVectorStore(),
      documentContents: "Brief summary of a movie",
      attributeInfo: [],
      structuredQueryTranslator: new SupabaseTranslator(),
