Desired outcome is this:

tahrir=> select persons.nickname, count(assertions.*) as assertions from assertions join persons on assertions.person_id = persons.id group by persons.nickname order by assertions desc limit 10;
  nickname  | assertions

I'm really not 100% on this one, but off the top of my head maybe something to this effect:

session.query(Person, func.count(Person.assertions)).join(Assertion).order_by(Person.assertions.desc()).limit(10).all()
