It looks like the answer to my question is no.
Is there any add-on (Elixer or whatever) which has a shortcut method like
what I'm asking?
I did find that "insert_or_update" is not the solution.
I also found an appropriate, but longer way to read or create:
page = Session.query(Page).filter(Page.url == url, Page.body==body).first()
if not page:
page = Page(url = url, body=body)
session.save(page)

page = Page(<primary key identifiers>)
persisted_page = Session.merge(page)
