The whole question of the database setup is an interesting one. If we
were to do anything at all here, I'd want to see not only the table
schemas and initial population, but also the hard-wired "vacuum" logic,
somehow made not so hard-wired. I have no good ideas about that. The
SQL commands could possibly be taken from scripts, but what of all the
work that's gone into friendly progress reporting for table loading?

I find this completely bogus. The data is delivered to the client,
ie it's inside the pgbench process. What's the grounds for arguing
that something else has to happen to it?
