GetAttributeByNum has first parameter as HeapTupleHeader, but most functions
use Datum and after that they call DatumGetHeapTupleHeader. The difference is
that DatumGetHeapTupleHeader performs detoast on tuple(row type).
Is it intention do not detoast in these functions or it is a bug?
thanks Zdenek
