Yep. pgbench is kind of my basic acceptance testing benchmark. If
you've got a 16 core 128G ram machine hitched onto a 100+15k5 SAS disk
san array and you're getting 20 tps on pgbench there's not much use in
running other benchmarks until you figure out what's so wrong.

It's also good for applying burn in loads over long periods. Nothing
like a week of running pgbench to find problems with RAID controllers,
drives, memory, cpus, cooling, power supplies or kernels. I had a
kernel bug on a server last year that took about 12 hours of heavy
pgbench to show up. Had a bad RAID controller that took 24 to 36
hours of pgbench to hang.

Plus, pgbench has the ability to run custom SQL for benchmarking, so
it's an easy way to build a custom test.
