He's already demonstrated that he has no clue what he's talking about,
so I think you can discount the rest ;-)
Serializability means that the database has to *give the illusion* of
one-at-a-time execution, not that it must actually do things that way.
Certainly we don't do things that way. See the extensive discussion in
the MVCC chapter of our docs.
