SysBench is an open-source benchmarking program originally targeted for use on MySQL databases. It can also be used for a variety of low-level system tests, from CPU to disk I/O.
When running the more complicate OLTP tests included, it has been known to some issues with locking on PostgreSQL, but at least read-only it seems to work fine.

- Running Sysbench 0.4.12 on Ubuntu 9.04: SysBench can be difficult to compile on some systems, this gives some suggestions for one popular combination.
