True, but then you don't get TPC-C, and dbt1 is ~= TPC-W. So with a
package of the full dbt suite (doesn't exist yet, but I suspect it
wouldn't be hard to change that), you get W, C, H, and eventually
TPC-App. Plus, much of what needs to be developed for our use-case would
benefit all dbt users, whereas pgbench is only of use to us internally.
dbt is also more flexable, since you can vary workload ratios. For
example, you can run dbt2 in a 90% read environment if you wanted.
