This test case seems much too far away from real world use to justify diddling low-level locking behavior; especially a change that is obviously likely to have very negative effects in other scenarios. In particular, I think it would lead to complete starvation of would-be exclusive lockers in the face of competition from a steady stream of shared lockers. AFAIR the existing behavior was designed to reduce the odds of that, not for any other purpose. regards, tom lane -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
