That's actually intentional. Alexander had changed those, and it made the patch a good bit harder to read because there's so many references. As the new thing is still a spinlock, just not a s_lock.[ch] style on, I don't see changing all that to be a significant benefit. - Andres -- Sent via pgsql-committers mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-committers
