SQLX扫描到结构数组

Question

I'm trying to implement a sql query that returns data in a way that jQuery Datatables expects while allowing users to customize the query (I'm doing alot of input validate to make sure there isn't any sql injection).The query is supposed to filter all of the edits by the object_name and editor display_name. Then of those edits it is supposed to get the last edit for each object based on it's perm_id (uid). Then it tries to fit everything into a jQuery Datatables friendly format that supports pagination. I think the query itself is working I'm just not sure if sqlx supports the array_agg scanning into a struct. When I try to scan it into the DataTableResponse struct I get this error.

unsupported Scan, storing driver.Value type []uint8 into type *[]edits.Edit

type Edit struct {
    Id                 *int            `db:"id" json:"id,omitempty"`
    UserId             *int            `db:"user_id" json:"user_id,omitempty"`
    PermId             *string         `db:"perm_id" json:"perm_id,omitempty"`
    ObjectName         *string        `db:"object_name,omitempty"`
    EditTypeId         *int            `db:"edit_type_id" json:"edit_type_id,omitempty"`
    EditDate           *time.Time      `db:"edit_date" json:"edit_date,omitempty"`

    DisplayName *string `db:"display_name" json:"display_name,omitempty"`
}

type DataTableResponse struct {
    Draw int `db:"draw" json:"draw"`
    RecordsTotal int `db:"records_total" json:"recordsTotal"`
    RecordsFiltered int `db:"records_filtered" json:"recordsFiltered"`
    Data []Edit `db:"data" json:"data"`
}


response := []DataTableResponse{}
err = db.Select(&response,
    fmt.Sprintf(`
        SELECT DISTINCT ON (results.perm_id) %d as draw, array_agg((%s)) as data,COUNT(DISTINCT perm_id) as records_total,COUNT(DISTINCT perm_id) - count(results.*) as records_filtered

    log.Fatal(err)
