Does PG issue checkpoint writes in "sorted" order ?
I wonder about something, too : if your DB size is smaller than RAM, you
could in theory set shared_buffers to a size larger than your DB provided
you still have enough free RAM left for work_mem and OS writes management.
How does this interact with the logic which prevents seq-scans hogging
shared_buffers ?
