+1, welcome.  It would be very cool to see SERIALIZABLE get faster.

This is a large commitfest so there's a pretty wide range of
interesting stuff to help out with, and many ways to help including
documentation, testing and code review.

One small patch that just might interest you, based on your interest
in SERIALIZABLE and also in parallelism, is my fledgling attempt to
connect those two features:


Unfortunately SERIALIZABLE support has not yet been included with a
couple of really important recent Postgres features: parallelism and
streaming replication.  I suspect the latter may be quite hard to fix
and the former quite easy.  If you're currently studying the
SERIALIZABLE internal data structures then you might like to review
that patch and tell me if my optimism is entirely misplaced, and
figure out how to test and break it...

That said, please pick anything that interests you!
