Ouch. I'll assume this was a typo from you as well, since *technically* triggers could be used to enforce uniqueness as well. Not just "only" unique indexes. And yes, *technically* those triggers could be disabled, and *technically* indexes could be dropped, blah, blah, blah. Not really that interesting though imo.
