    Right,  they  have.  But  PostgreSQL  doesn't and so PL/pgSQL
    can't.  PL/pgSQL cannot do any thing that  a  C  function  in
    PostgreSQL cannot do. The PL handler is written in C and that
    is what the executor calls instead of the compiled  function.
    From  the  backends point of view, a PL handler is just one C
    function with a bunch of personalities.
