The last presentation I saw from Volt guys explicitly mentioned
Postgres as one of the elephants.
Also, if you read their literature carefully, you discover that the
reason there's no locking overhead is because there's no lock;
basically, if you're joining a lot, you're thrown back on
old-fashioned locks of some sort. They also don't permit
in-transaction round trips to the application, so that source of lock
contention is also gone.
