Your own Postgres

Already have a Postgres? Point Tuck at it instead of the bundled one.

  1. Set TUCK_DATABASE_URL in .env, with sslmode=require.

  2. Start the external-database compose file:

    docker compose -f docker-compose.external-db.yml up -d

Tuck keeps everything in its own tuck schema, so it can share a database.

Supabase​

Use the session pooler string from project settings → database:

TUCK_DATABASE_URL=postgres://postgres.PROJECT_REF:PASSWORD@aws-0-REGION.pooler.supabase.com:5432/postgres?sslmode=require&pool_max_conns=5
  • Not the direct host, which is ipv6 only.
  • Not the transaction pooler on port 6543, which breaks Tuck's queries.
  • Url-encode symbols in the password: @ is %40, # is %23.
