Scanner should return one of int64,float64,bool,[]byte,string,time.Time,nil , but I got uint64

It maybe a bug of database/sql , if it is ,please tell me.

### Issue description
https://pkg.go.dev/database/sql#Scanner says Scanner should return one of int64,float64,bool,[]byte,string,time.Time,nil , but I got uint64

### Example code
the sql:
```
select * from INFORMATION_SCHEMA.TABLES
```
some of my scaner_t implement.
```go
type scaner_t struct{
src any
}
func (s *scaner_t) Scan(src any) error{
s.src = src
return nil
}
func (s *scaner_t) AsString() (outS string,err error){
switch obj:=s.src.(type) {
case int64:
return strconv.FormatInt(obj,10),nil
case float64:
return strconv.FormatFloat(obj,'f',-1,64),nil
case bool:
return strconv.FormatBool(obj),nil
case []byte:
return string(obj),nil
case string:
return obj,nil
case time.Time:
b,err:=obj.MarshalText()
if err!=nil{
return "",err
}
return string(b),nil
case nil:
return "",nil
default:
return "",errors.New("unknow type "+fmt.Sprintf("%T",s.src))
}
}
```

### Error log
