Hey, pg_bench is a good start on a Postgres performance tester, and it's much,
much better than what there was before you came along ... which was nothing.
Thank you again for contributing it.
pg_bench is, however, only a start on a performance tester, and we'd need to
build it up before we could use it as the basis of a PG tuner.
