You mean the standard message "trigger failed", right?

What I did is create a function that searches for child records, before trying to delete. If there are child records, I show my own message instead. I used the same message for all tables: "The record is being used in table (tablename)".

I don't have the corresponding function available right now, but I can search for it when I am back at home, in about a week, if you are interested.
