small cleanup pl_exec.c

Hello,

function exec_set_found uses a PointerGetDatum, should be BoolGetDatum

***************
*** 5860,5866 ****     PLpgSQL_var *var;
     var = (PLpgSQL_var *) (estate->datums[estate->found_varno]);
!     var->value = PointerGetDatum(state);     var->isnull = false; }

--- 5860,5866 ----     PLpgSQL_var *var;
     var = (PLpgSQL_var *) (estate->datums[estate->found_varno]);
!     var->value = BoolGetDatum(state);     var->isnull = false; }
