A crosstab is also known in MS Excel as a "pivot table", if that helps
any.  It facilitates drag-and-drop data analysis by creating arbitrary
2-D matrices aggregated from data columns.  Very cool, and hard to
adequately describe, as it makes some complex operations very simple, and
I don't understand how it works underneath.  IMO, it is one of the most
powerful data analysis tools in existence.  It would be neat to be able
to do something similar in pgsql...
