This book is the official documentation of Pgpool-II. It has been written by the Pgpool-II developers and other volunteers in parallel to the development of the Pgpool-II software. It describes all the functionality that the current version of Pgpool-II officially supports.
To make the large amount of information about Pgpool-II manageable, this book has been organized in several parts. Each part is targeted at a different class of users, or at users in different stages of their Pgpool-II experience:
Part I is an informal introduction for new users.
Part II describes the installation and administration of the server. Everyone who runs a Pgpool-II server, be it for private use or for others, should read this part.
Part III explains several configuration examples so that users can choose the starting point of their actual systems.
Part IV contains reference information about SQL commands, client and server programs. This part supports the other parts with structured information sorted by command or program.
Part V is an appendix information such as release notes.
