What are you trying to accomplish? "CREATE OR REPLACE FUNCTION trigger_x()" does not declare any formal-parameters, so
callingit with arguments doesn't make sense. I'm surprised creating the other triggers didn't produce an error stating
"Nofunction defined with the name trigger_ix and the given argument-type".
