Trigger functions must return TRIGGER; the function you posted
returns BOOLEAN. If you change the return type to TRIGGER then the
above error should go away. However, the function also has several
syntax errors.

The above line and a few others are missing THEN.

INT should be INTO.

This line is missing a trailing semicolon.

Use PERFORM to call a function for its effects and ignore its return
value. Or did you mean to assign the return value to a variable?

ENDIF should be END IF.
If you make the indicated changes then the function should be created
successfully. I didn't look closely at the logic, so whether it'll
actually work is another matter ;-)
