It seems grossly irresponsible to encourage the use of serializable without even mentioning deadlocks. I guess you won't have deadlocks if your db interprets as serializable as "lock the whole database on transaction start", but that means literally no concurrency whatsoever, which also seems like a grossly irresponsible recommendation.
I dunno, maybe I didn't get the memo that the database of the future will be single-threaded.
