I'd be inclined to put aggregates, transactions, foreign keys, and views
into the "intermediate" category, leaving only inheritance as
"advanced".  (Or maybe we should just drop inheritance from the tutorial.)
You could possibly even argue that joins are intermediate instead of
basic, although that's stretching it a bit.

I agree with Peter's point that the first thing to teach is how to get
data in and out.



You could add triggers, rules into advanced features... You could also break joins up so that when
talking about outer, left etc... it goes into advanced but basic "join on" or natural joins are in
intermediate.
