pgbench may not be the setting in which that can be shown.  It's I/O
bound to start with, and it exercises some of our other weak spots
(viz duplicate-key checking).  So I'm not really surprised that it's
not showing any improvement from 7.1 to 7.2.

But yeah, it'd be nice to get some cross-version comparisons on other
test cases.
