Re: pg_prewarm

So I wrote a prewarming utility. Patch is attached. You can prewarm either the OS cache or PostgreSQL's cache, and
thereare two options for prewarming the OS cache to meet different needs. By passing the correct arguments to the
function,you can prewarm an entire relation or just the blocks you choose; prewarming of blocks from alternate relation
forksis also supported, for completeness. Hope you like it. <blockquote
