>    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.
   </P
><P
>    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.)
