As I figured out `ScanStructs` function does `SELECT *` by default and maps columns returned by query to struct's fields. This may lead to `goqu: unable to find corresponding field to column \"column\" returned by query` error after adding new column to table. Is there any way to select only columns defined by struct's db tag within goqu library? FYI, there is [huandu/go-sqlbuilder](https://github.com/huandu/go-sqlbuilder/blob/master/struct.go#L281) which provides quite useful feature to select columns based on struct's fields with certain `db` tag which provides this function.
