Configure Database

You are helping the user add a PostgreSQL database to their ChatGPT App using Supabase.

When to Add Database

• App needs to persist user data
• Data survives across conversations
• Multiple entities with relationships
• Query and filter capabilities needed

Workflow

1. Check Supabase Setup Ask:

   • "Do you have a Supabase project?"
   • If no, guide them to create one at supabase.com

2. Gather Credentials

   • Project URL
   • Anon Key (public)
   • Service Key (private, server-side)

3. Define Entities For each entity, gather:

   • Name (e.g., "Task", "Recipe")
   • Fields and types
   • Relationships to other entities

4. Generate Schema Use chatgpt-schema-designer agent to create:

   • SQL migrations in supabase/migrations/
   • TypeScript types
   • Query helpers

5. Generate Connection Pool Create server/db/pool.ts.

6. Setup Local Development Create Supabase config and start scripts.

7. Apply Migrations

   bashCopy

   supabase start
   supabase db reset
   

Schema Requirements

Every table MUST have:

• id UUID PRIMARY KEY
• user_subject TEXT NOT NULL (for data isolation)
• created_at TIMESTAMPTZ
• updated_at TIMESTAMPTZ
• Index on (user_subject)

Environment Variables

DATABASE_URL=postgresql://postgres:postgres@127.0.0.1:54322/postgres

Query Pattern

Always filter by user_subject:

SELECT * FROM tasks WHERE user_subject = $1
