Does web2py/PyDal support rowvalues?

[Dave S]

While stumbling around some newsgroups (when recovering my .newsrc file and tweaking the subscriptions) I found a discussion of using rowvalues+limitby for paging rather than offset+limitby.  Since modern SQLites support this (as, of course PostGres does),  I'd like to play around with it in the PyDal enviornment, but I don't think this is covered in the web2py book.

Thanks.

Dave
