While pgbench might be "simple" program, as in a test-runner, workloads that are run by it are far from it. It runs TPC-B by default but can also run your own arbitrary script that defines whatever the workload is? It also allows to run queries concurrently so I fail to understand the reasoning of it "being simple" or "microbenchmarkey". It's far from the truth I think.
