Summary
The new release has countless new features and it is close to impossible to mention them all. During the development cycle, well over 2,000 commits have happened and thousands of things have been improved.
Some of the key features, such as fault-tolerant COPY and improved partitioning, have long been awaited and finally made it into the core. Things such as incremental base backups will significantly reduce the cost of large-scale PostgreSQL deployments. And other features simply lead to a way better user experience.
Therefore, relax, lean back, and enjoy the brand-new release of PostgreSQL, which will be covered in this book in great detail.
In Chapter 2, Understanding Transactions and Locking, we will discuss important concepts such as transactions and locking, which form a core component of every relational database system.
