This has proven to be a very good book. I'm not a database expert, but I happen to need PostgreSQL because I am working on a project that involves GIS, and PostGIS turns out to be a very appropriate tool for what I am doing. This book got me started and has helped me through the importing of data, understanding basic functions, and incorporating PostgreSQL into my programs (I use a combination of R, Python/Jython and Java. The book does not talk about them all, but what is in there carries over pretty well.) I've also used this to use BIRT and Openoffice.org to link my PostgreSQL databases. Again, it is not spelled out, but what was in here brought me well along the way to making it work.
This book concisely describes the way of dealing with PostgreSQL environment. It also describes functional abilities, which is common in most known DBMSes and does not contain the distinctive features of PostgreSQL.
