I've seen no evidence saying that random_page_cost needs to be decreased
for modern hardware. Disk seek speed versus bandwidth hasn't changed
that much.
People sometimes find it profitable to decrease that setting to
compensate for other optimizer issues, but that doesn't mean we
ought to change the default.
As for the other settings you mentioned, I'd agree that the defaults are
pretty arbitrary, but what evidence have you got to suggest better ones?
