Excerpts from Samuel Gendler's message of sáb oct 16 02:35:46 -0300 2010:

> An issue with automatically analyzing the entire hierarchy is 'abstract'

> never query across the abstract table, only the parent table of each
> aggregation granularity

Hmm, I think you'd be better served by using LIKE instead of regular
inheritance.
