Nullable types for computed columns?

[gabrielhora]

Hi there,

I'm trying to come up with a solution for having nullable types for computed columns.
I know I can override table column types via overrides in sqlc.yaml, is there a way to do the same for queries?

This is a simple example, min and max may return null. How can I deal with this in sqlc?

const test = `-- name: Test :one
select min(age)::int as min_age, max(age)::int as max_age from my_table
`

type TestRow struct {
	MinAge int32
	MaxAge int32
}

func (q *Queries) Test(ctx context.Context) (TestRow, error) {
	row := q.db.QueryRowContext(ctx, test)
	var i TestRow
	err := row.Scan(&i.MinAge, &i.MaxAge)
	return i, err
}

Thanks a lot for your time.
