It would be nice if this had an option to preload only internal B-tree pages into shared_buffers. They're usually less than 1% of the total pages in a B-Tree, and are by far the most frequently accessed. It's reasonable to suppose that much of the random I/O incurred when warming the cache occurs there. Now, prewarming those will incur random I/O, often completely random I/O, but by and large it would be a matter of swallowing that cost sooner, through using your tool, rather than later, during the execution of queries. -- Peter Geoghegan -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
