thanks Adrian, exactly what I was missing :-) about knowing if I should... We have to create a set of triggers (insert, update, delete) within a huge set of tables. and that list of tables, and structure of them can be customized, maintained, ... so we were looking for a standard script to automatize the building of the whole thing, taking list of columns and constraints (for PK) directly from pg_catalog. Now it works :-)
but.. why do you ask that question ? is there any king of hidden wolf we didnt see ?
