Rather than putting a rating on a section, I would say let's leave the normal
and advanced section as it is and add another section which illustrates
"applying" postgresql/RDBMS to solve real problem.

e.g. illustrate how do you normalize and maintain foreign keys to integrity.
Then add cascade clause. Then views for denormalizing it.

If we illustrate a real world situation, it will be easy to grasp even if it
spans multiple concepts. And at the end of it cross reference to details
pages at the end of each illustration.

That way it will be bit more handholding rather than trying to gulp various
theoretical pieces.

I am going to save that list or search later in archives...:-) Plan to work on
it if I get time.

Just a thought..
