Per discussion, the old value of 128MB is ridiculously small on modern machines; in fact, it's not even any larger than the default value of shared_buffers, which it certainly should be. Increase to 4GB, which is unlikely to be any worse than the old default for anyone, and should be noticeably better for most. Eventually we might have an autotuning scheme for this setting, but the recent attempt crashed and burned, so for now just do this.
