With procedures we can be in conformance with ANSI standard and others
databases. New SQL2006 standards contains lot of SQL/PSM code and will
be usefull, if we can port this code without changes.

New calling convention can simplify life. It can support more than one

C code, because I have to do create tuple when I would to return two
ints ...
