An immediate hack comes to mind. Post it to a temp table, and have a super-user level trigger copy it out and update the real table. How the one functions gets to be super user, is beyond my knowlege. :-(

Interesting, but i supose i´m left with the same security problem, i don´t want the user to have direct access on update to that table, i wanted to restrict it to functions. From where i see it, this temp table would efectly give permission to update the real table, please correct me if i´m wrong.
and about the functions gets to be super user, i was thinking more around the possibility of getting the onwer´s permission, can this be done? :-(
 
thx,
