Thanks a lot for the response Andrej!
One of these texts was known for me. But all of them are VERY basic. No one explains how to do a query and manage results :(
The only one that manage querys is the source code placed at contrib/tablefunc in the Postgres distribution. But is VERY hard to follow for me :( I would like to find an intermediate step.
Thanks again
Emiliano
