Before he does that, wouldn't it be more useful, to find out WHY he has so much IO?
Have I missed that or has nobody suggested finding the slow queries (when you have much IO on them, they might be slow at least with a high shared memory setting).
So, my first idea is, to turn on query logging for queries longer than a xy milliseconds, "explain analyse" these queries and see wether there are a lot of seq scans involved, which would explain the high IO.
Just an idea, perhaps I missed that step in that discussion somewhere ...
But yes, it might also be, that the server is swapping, that's another thing to find out.
