In addition to these, there's actually a nice set of sample primitive
operations to test included in the "Advanced transactional" section of
sysbench: http://sysbench.sourceforge.net/docs/#database_mode
I have code that does this sort of thing, including tests at multiple
client loads, that even spits out HTML for the results. It's based on
pgbench and I sent out hundreds of results generated by it when I was
doing the background writer optimization. The results are thoroughly
boring on just my system, and I'm just waiting for a larger server to be
available before it's worth my trouble to revive that project. Once such
a system becomes available, I could have a basic set of tests like these
ready the day after I get a login.
That's not to say what you're talking about isn't needed, because using
pgbench introduces some limitations and buildfarm integration is a whole
different topic. But I have made a first move here and only need the
hardware to become available before I can produce something useful with
it.
