cannot query table data without a specific column type

I got the following errors:

`dest[0] types must be *[]byte or *string`

when I try to fetch all the data via:

```golang
cols := make([]any, 3)
sd.Scan(cols...)
```

Start by locating the Scan implementation and reproduce the reported call with cols := make([]any, 3) and sd.Scan(cols...). Trace where the `dest[0] types must be *[]byte or *string` error is produced; done means table data can be fetched without specifying a concrete column type.
