+ <para>
+ <acronym>SQL92</acronym> defined three feature sets for
+ compliance: basic, intermediate, and advanced. Most database
+ products claiming <acronym>SQL</acronym> standards compliance were
+ compliant at only the basic level, since the entire set of
+ intermediate and advanced features was either to voluminous or in
+ conflict with legacy behaviors.
+ </para>
+
+ <para>
+ <acronym>SQL99</acronym> defines a large set of individual
+ features rather than the ineffectively broad three levels found in
+ <acronym>SQL92</acronym>. We list the entire set of features
+ defined in the standard, with comments on those features not yet
+ implemented in <productname>PostgreSQL</productname>.
