On a quick skim I don't think this is related to serializable
database transactions.  It might be useful for PostgreSQL in terms
of more efficient lightweight locks within the server memory space,
but that's an internal implementation issue, not anything which is
user-visible beyond its performance characteristics.  I'll give it a
closer read when I get a chance.

Probably not.  This is getting really close to the metal, and
because of portability concerns PostgreSQL doesn't have a lot of
that.
