One of the other reasons for moving to rails was the holy grail of  
using postgres, and rails is theoretically db independent. Of course  
it didn't work out that way.

On the specific point, I'm all for more speedy SQL on things like that  
so long as there is a rails logic way too - in much the same way as  
there apparently is with the tileid stuff. Then if things change  
significantly (like, say with changesets, rollback, spatial data  
types) we don't have limited options.
