Yeah, I was wondering what a fool-proof way of doing that would be, without implementing a new feature. Turning synchronous_commits back on and then doing and committing a transaction guaranteed to generate WAL would do it. Would a simple 'select pg_switch_xlog();' always accomplish the desired flush?
