Обсуждение: modifying a TupleTableSlot

If I have a TupleTableSlot, and I need to obtain another TupleTableSlot with
a different TupleDesc (same fields but different order). Is there a way to
do it without that I go myself and try to retrieve the fields and form the
tuple myself? In other words, are there functions already in postgres that I
can use together to reach this?

Regards,

The CVS-tip junkfilter code is a reasonable prototype for this.
