PostgreSQL 18 introduces significant enhancements for developers, including native UUID v7 support, virtual generated columns, and improved RETURNING clause functionality. These features aim to streamline development processes and improve database performance. Additionally, the EXPLAIN command now provides default buffer usage information, enhancing query analysis.

Understanding the fundamentals of PostgreSQL can significantly enhance your workflow by demystifying its operations, which fundamentally revolve around file manipulation. By moving beyond the default package manager installations and engaging with the system manually, users can improve debugging, provisioning, and overall control of their database environment. Embracing this approach allows for a more confident and efficient development experience.

Git can serve as an unconventional database alternative for certain projects, offering features like built-in versioning, atomic transactions, and fast data retrieval, although it has notable limitations compared to traditional databases like PostgreSQL. The article explores Git's internal architecture through the creation of a todo application, demonstrating its capabilities and potential use cases. However, for production applications, utilizing established database services is recommended.
