What's the page buffers value at database-level?

This would multiply your 80 MB (under the assumption that your databas
page size = 4K) by the factor of 100. ;-)

No.

When switching from Super to Classic, a number one reason why you
*might* see worse performance with Classic is a too high page buffers
value in combination with quite a number of concurrent users eating all
your servers RAM.
