Wait a minute. This patch changes the behavior so that
LockBufferForCleanup is applied to *every* heap page, not only the ones
where there are removable tuples. It's not hard to imagine scenarios
where that results in severe system-wide performance degradation.
Has there been any real-world testing of this idea?
