OK, maybe that doesn't matter.

Erm ... exactly why couldn't you do that before?

pgbench doesn't have all that many things to recommend it, but what
it does have is that it's been a stable testbed across quite a few
PG releases.  Arbitrarily whacking around the tested functionality
will destroy that continuity.  I fell into this trap before myself
... I have a local copy of pgbench that produces TPS numbers quite
a lot better than the standard pgbench, against exactly the same
server.  What's wrong with that picture?
