I think you're assuming that 7.3 section numbers would apply to 7.4,
which they don't (the html page names are somewhat more likely to carry
across, though).

In 7.3 and before the situation is even more confusing because the docs
are made up of several separate "books" each with its own chapter
numbering.  "Rules vs. Triggers" is section 13.7 of the Programmer's
Guide book (in 7.3 anyway), whereas you seem to have been seeking it in
the Administrator's Guide.

7.4 has just one chapter numbering sequence for the entire SGML document
set, which I think is a considerable improvement.  We're not going to be
revisiting the 7.3 documentation though.  My advice: update to 7.4 ;-)
