Zero Side-Effect Database Testing: No Docker, No Cleanup Scripts

Most database tests are slow because of Docker or flaky because of shared state. In this video, we explore how pgmi uses a recursive savepoint algorithm to provide instant test isolation without teardown scripts. Learn how to implement gated deployments where your database changes only commit if your tests pass." Key Concepts to Cover (Based on Sources) To fulfill the promise of these titles, the video should cover: 1. The Persistence Problem: Explain how database testing is harder than code testing because state persists. 2. The Savepoint Solution: How pgmi wraps each test in a savepoint and rolls it back, ensuring zero side effects. 3. Hierarchical Fixtures: How subdirectories inherit data from parent _setup.sql files. 4. Transactional Atomicity: The ability to combine BEGIN, DDL, TEST, and COMMIT into one atomic operation, a feature unique to PostgreSQL's transactional DDL GitHub: https://github.com/vvka-141/pgmi
