The 'migrate to PostgreSQL when a second writer appears' advice hides a cost: the migration changes SQL dialect details, types, and transactional behaviour, and happens exactly when the service has grown and is hardest to change. Starting with PostgreSQL costs one container and avoids the later migration. For anything expected to grow, that is the safer bet.
