Quite, but in the meantime, a good benchmark should stress the system
enough to cause crashes, lockups or at least incorrect results if a
bug is introduced in the shared memory or semaphore code, and will
definitely reveal any slowdowns introduced by new code, so my question
is: where can I find a good benchmark for PostgreSQL?  Note that I
don't care about comparing PostgreSQL to other RDBMSes; I just want to
a) test PostgreSQL under high concurrent load and b) if possible,
measure the performance impact of a patch.
