   Triggers do accept parameters. In fact when you type CREATE TRIGGER
you can also specify some arguments. They are accessible via trigdata
not by the standard args of a function (in fact a trigger function must
not have parameters). The manual makes an example of passing the
current_user to a trigger, but it is not clear to me. Can anyone explain
how to make it works?
