Installation:

In order to install postgresql on your system, follow the instructions(short version) mentioned in 'install' file after extracting postgresql-9.1.2.tar.gz

Utilities:

The postgresql code is quite huge with lots of directories and source files. In order to make life easier while exploring the code, use either an IDE such as eclipse, or tools like cscope, ctags that make browsing through the code simpler. We strongly recommend using a debugger to trace what happens when you run a command or query in PostgreSQL.
