On page 10 of the POSTGRES user manual, there is an example
    that defines a function high_pay. It is as the following.

     define function high_pay
     (language = "postquel", returntype = set of EMP)
      as "retrieve (EMP.all) where EMP.salary > 50000" \g
    
    Question: It is not shown how such function may be used
    in a query.  Please give an example for this 
    particular case. E.g., in a retrieve to EMP.

    Thanks in advance,
