Hi,

It was good to see you in Japan.

PostgreSQL Enterprise Consortium (non profit PostgreSQL related
organization in Japan. http://www.pgecons.org) is about to inspect the
performance impact of the checksum using High-end PC server (real 80
cores with 2TB memory). What in my mind is using pgbench with custom
query (purely SELECT). Is there any recommendations/suggestions in
doing that?

(The result will be in public of course).
