execute procedure material() ?
Your function example below creates a function named partSumm() and it
looks as if you have a table named "material" in the DB.
Perhaps you have by mistake also created a function named material.
don't know on Pg8 but on earlier versions, you can't register a
trigger to a procedure that doesn't exist.
So, your trigger doesn't run the function that you believe it does.
