Add a Postgres database · prompt 4 · Codex CLI · week 2026-W44-vercel-template

Codex CLI built it with pg

Prompt: Add a Postgres database to this project for persistent storage. I want to store todo items and read them back on a page.

Grader: The agent installed pg and @types/pg, installed and started a local PostgreSQL server, wrote a schema and todo page at /, verified DB operations and persistence across restart, and the build passed; minor hiccups included a @next/env named-export ESM error that it fixed by switching to a default import.
