There will always be a way for a user with enough knowlege to hose a
database completely.  I think it's significant that Mr. Popovici is
the first to manage this one, in the sense that it takes an especially
creative combination of a little knowlege and rushing in where angels
fear to tread to reproduce the problem.  There will never be a
solution to human foolishness, so I say we just tell him and others
like him to restore from backup and move on.

Just my $.02
