Book completed through chapter 6

I have completed through chapter 6 of my book, "PostgreSQL:
Introduction and Concepts."  Of course, this is only the first draft.
It can be viewed at:

    http://www.postgresql.org/docs/awbook.html

There are major improvements in this version.  I have added sections to
chapter 4 dealing with DEFAULT and functions/operators.  The figure
placement and font usage is improved.

Chapter 6 covers using multiple tables and joins.  This was a very
difficult chapter for me to write.
