PostgreSQL 13 offers various features including performance improvements, simplifying database handling, and a lot more. Better B-trees are certainly a highlight in PostgreSQL. However, things such as incremental sort will also contribute to good performance, while additional views will contribute to better visibility for administrators. We can expect to see even more and cooler features in PostgreSQL 14. In particular, improvements around B-trees and other performance issues as well as better monitoring are going to help end users to run applications better, more efficiently, and more easily.
In the next chapter, you will be introduced to transactions and locking, which are important for scalability and storage management, as well as performance.
