Add a Postgres database · prompt 1 · Codex CLI · week 2026-W44

Codex CLI built it with pg

Prompt: Add a Postgres database to this Next.js app. Create a `notes` table and a page that lists notes from it. Install whatever you need and make `npm run build` pass.

Grader: The agent installed pg and @types/pg, set up a local Postgres with a repeatable notes migration, and built a server-rendered page that lists notes, then verified empty and populated states against the database while the build passed; it did not cite any fetched documentation URLs.
