I find this pretty fishy. The extreme similarity of the 4-client
numbers seems improbable, from what I know of the two databases.
I suspect your numbers are mostly measuring some non-database-related
overhead --- communications overhead, maybe?

7.3 should be a little bit better because of Manfred's work on reducing
tuple header size --- if you create your tables WITHOUT OIDS, you should
save 8 bytes per row compared to earlier releases.
