I think I've run into this problem before where I needed to address the 
select by name; IIRC, I think the trick was using `.subquery()`.

Aside from it being more correct in certain situations, the problem had to 
do with the the existence (or non-existence) of parenthesis in the compiled 
query across backends, and if the clause was given an automatic alias or 
not.  Postgres would allow a 'not entirely correct' query and do as I 
intended, but Sqlite could not handle it.  

IIRC there are also some ways to use `.select()` in queries like this.

The above works, so keep it.  I'm just bringing this up for future 
reference.
