BTW, here's a counter-intuitive solution if using pgbouncer is not possible. Simply drop and reestablish connections on every request. In theory this is horrible, since PG connections are so expensive. In practice the cost of establishing a connection is negligible for a Rails app. I do suspect this will make performance "fall-off-the cliff" as you get close to capacity.
