Sure, maybe for PostgreSQL 9.1 But the immediate problem is older releases (8.1 - 9.0) specifically on Linux. Something as innocuous as re-building your DB on a newer kernel will radically affect performance -- even when the DB kernel didn't change. So I think we should aim to fix old versions first.
