Typerel is only for defining the 'allowed relations'. It is only used during creation 
of relations
and while optimizing queries. It has no other function.

Indeed this means that you cannot simply list in insrel to find A-related-A, because 
the type of the
nodes is not in that table (the only thing present is the 'rnumber' which only 
indicates 'related'),
you need to somehow do a join for that.
