Afraid not. It might be possible to implement in the simple case, but
what with views rewriting queries and triggers issuing their own
secondary queries it's not always obvious what "the" query would be.
What we really need is NEW and OLD as sets of affected rows in
statement-queries. Unfortunately that's not implemented yet either -
it's on the TODO I believe though.
