    // this means we won't be able to correctly infer the types
    // for dynamic parameter markers (SET x = ?).  But
    // maybe validateUpdate and validateInsert below will do
    // the job?

    // since validateSelect() would bail.
    // Let's use the update/insert targetRowType when available.
