I guess i don't understand why this is not working. Is it just because of the *on* key?
Of couse this will fail.

```sql
select distinct on (album) from tracks order by album;
```

But this is working.

```sql
select distinct(album) from tracks order by album;
```

Shouldn't the database adapter abstract this syntax detail?
So that i can write:

```ruby
DB[:tracks].order(:album).distinct(:album)
```
