Definitely, but my argument is that OSes must account for the shared-server case, but in practice many servers are dedicated to a single service.
Supposing you built a memory manager exclusively tuned for PostgreSQL, with the assumption that it has the machine to itself. That memory manager would have a different performance profile from the kind of "veil of ignorance" that a general-purpose memory manager has to cope with.
