DX: Assertion Testing

✅ Diff

The PR provides a comprehensive guide for setting up a local Postgres database using Docker which is useful for new users. The instructions are clear, and the addition of Adminer offers a simple way to manage the database. Highlighting commands and the ports section improves usability by drawing attention to key information.

✅ Integrated

The PR's integration with the entire set of changed files supports overall usability by providing an easily accessible guide for setting up a local database, which is referenced from relevant places within the documentation. Connecting this new guide with the '_01-connect-a-source.mdx' file and updating the quickstart to mention the local setup option enhances the flow and makes it easy for users to find tools to start a local database when needed.
