The CD included with this book contains the common programs that PostgreSQL users utilize. The CD also includes the PostgreSQL application server LXP. The following is a listing of what is on the CD, including a short description of each package.
The community version of PostgreSQL in source form. It is the most actively developed PostgreSQL. We do not provide binaries of PostgreSQL, as you may want to compile different features.
An evaluation/developer use copy of the LXP PostgreSQL application server. LXP is a good tool for integrating PostgreSQL (and other technologies) with the Web.
The source code to the Python programming language (one of our favored languages). The CD also contains the PostgreSQL driver.
The source code to the Perl programming language, often called "the glue of the Internet."
The source code to the PHP programming language, one of the most oft-used web languages available.
