Right, it's just used for planning. Avoid setting it too low, if it's
below about 2.0 you would most likely see some very strange plans.
Certainly it doesn't make sense at all to set it below 1.0, since that
is saying it's cheaper to get a random page than a sequential one.
What was your original random_page_cost, and what is the new value you
set it to?
