You need to give PG a CHECKPOINT command to flush stuff out of its
internal buffers. After that finishes, a manual "sync" commnd will
push everything down to disk.
You realize, of course, that a system failure while the updates are
running might leave your database corrupt? As long as you are prepared
to restore from scratch, this might be a good tradeoff ... but don't
let yourself get caught without an up-to-date backup ...
