Trigger question

Hi there.

I'm trying to use triggers for the first time, but I'm having some
problems.

Here's my SQL:

create function set_counter()
returns opaque
as 'BEGIN
    new.count := 0;
    RETURN new;
    END;'
language 'plpgsql';

create trigger set_counter after insert or update on nivel
for each row execute procedure set_counter();


count is an int, and its default value is -1.

The problem is that after I insert something, count value is still -1,
not 0!

Could someone tell me what's wrong?

Thanks
