small cleanup pl_exec.c

Hello,

function exec_set_found uses a PointerGetDatum, should be BoolGetDatum

*** pl_exec.c.orig	2011-11-24 12:51:45.000000000 +0100

***************
*** 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;
}
