Summary: Touched too many things, but not very deep on anything
Review: This book touched too many things but with very shallow coverage on each subjest. It looks a direct copy from the online documentation. It is a pure waste of trees. In certain places, the author missed very important things. For example, the ExecCommandOk command is totally missed from this book.As an reference book this book is too shallow. As an tutorial it is not good enough.

Summary: Excellent Resource
Review: This is a great PostgreSQL book, better in my opinion than the O'Reilly or Wrox book. They are all better than the book by Perkins. This book is for someone who knows a little bit about SQL and databases. The chaper on SQL is not too large, which is exactly what it should be. There are enough SQL books! The SQL chapter is to-the-point, more as an overview of available SQL functionality in the database. The O'Reilly book spends too much time being a SQL tutorial, combine that with a chapter on some product for Apache called LXP, and a whole section on commands, you are left with pretty much 50% of the book dedicated to SQL. An end-user, with little database or SQL experience will probably like the Wrox book best. Someone who is going to administer PostgreSQL or a developer (especially a developer) will probably find this book more suited to their skill level and requirements. The book is well written and covers most of the major items of concern. Part II of the book includes real world examples, which are very helpful. The largest chaper is chapter 9, which covers programming interfaces between various languages such as C, Perl, Python, PHP, Java, etc. There is also a helpful chapter on dealing with binary data and date calculations. In my opinion, this book, along with the New Riders reference book, work well together.
