Well, this isnt easy to code then, especially since every “limit by” case would have to be coded specifically.
Maybe just remove this feature for non-sql backends (there arent any, so far, anyhow). But then I haven’t seen gdbm on a NSLU2, which is supposedly faster and scales better *shrug*
Still I’d say that recoding this part is not for the faint of heart.
