ANALYZEnow - how often is it recommended to do this?
PostgreSQL's defaults are based on extremely small and some would say
(non production) size databases. As a matter of course I always
recommend bringing seq_page_cost and random_page_cost more in line.
However, you may want to try moving random_page_cost back to 4 and try
increasing cpu_tuple_cost instead.
