That's even better -- I tried regproc, but forgot about regprocedure. I
think the problem will be, though, that the output of the reg* datatypes
is not castable to text, and therefore cannot be used to build a dynamic
sql statement.

   select 'GRANT EXECUTE ON ' || 1142::regprocedure;
   ERROR:  array value must start with "{" or dimension information

But with the help of plpgsql:

   create or replace function regprocedure2text(regprocedure)
   returns text as '
     begin
       return $1;
     end;
   ' language plpgsql;
   CREATE FUNCTION
   select 'GRANT EXECUTE ON ' || regprocedure2text(1142::regprocedure);
                   ?column?
   -----------------------------------------
    GRANT EXECUTE ON date_mii(date,integer)
   (1 row)
