So your 'novalidate' referred to the

    "without validation"
clause of exchange; I thought you
were referring to the workaround
for uk/pk exchanges where even if you
did

    including indexes without validate
on the exchange, Oracle still did a
horrendous check of the UK and PK
constraints by doing a massive MINUS
and INTERSECTION across the entire
partitioned table.
