Here's your problem; you've created a function with a varchar parameter
...
> ERROR: CreateTrigger: function check_participant() does not exist
... and you're then calling it with no parameters. check_participant()
and check_participant('some string') are two different functions, as
would be check_participant(Numeric, Int) if you created it.
However, the function you have is otherwise inappropriate; it returns
values to the screen (not possible with a trigger), takes a parameter,
and does not return NEW. What are you trying to do, exactly?
