Regarding this last, Oracle has an equivalent - rowid. In the web
toolkit I'm helping port, it's used somewhat often, and having oid
available has been a convenience.
Having said that, its use in this toolkit's could be replaced by
simply creating a sequence and numbering rows by hand. Their loss
wouldn't bother me particularly even though it would add a little
work (not much) to this project.
