This is fantastic. The documentation is extensive and easy to follow, but the biggest value to me are the numerous illustrations.
I was superficially familiar with some of the concepts, but the illustrations are helping my truly understand them. Just look at the official documenation of the WAL, and then this book's depiction of it in chapter 9.
Also, nice to see that the material is current (as of PostgreSQL 9.5).
