> In the previous chapter we have covered the basics of using
<ACRONYM
CLASS="ACRONYM"
>SQL</ACRONYM
> to store and access your data in
<SPAN
CLASS="PRODUCTNAME"
>PostgreSQL</SPAN
>. We will now discuss some
more advanced features of <ACRONYM
CLASS="ACRONYM"
>SQL</ACRONYM
> that simplify
management and prevent loss or corruption of your data. Finally,
we will look at some <SPAN
CLASS="PRODUCTNAME"
>PostgreSQL</SPAN
>
extensions.

> This chapter will on occasion refer to examples found in <A
HREF="tutorial-sql.html"
>Chapter 2</A
> to change or improve them, so it will be
useful to have read that chapter. Some examples from
this chapter can also be found in
<TT
CLASS="FILENAME"
>advanced.sql</TT
> in the tutorial directory. This
file also contains some sample data to load, which is not
repeated here. (Refer to <A
HREF="tutorial-sql-intro.html"
>Section 2.1</A
> for
how to use the file.)
