Can I ask for some help with benchmarking? There are some results here that show PostgreSQL is slower in some cases than Monet and MySQL. Of course these results were published immediately prior to 8.2 being released, plus run out-of-the-box, so without even basic performance tuning. Would anybody like to repeat these tests with the latest production versions of these databases (i.e. with PGSQL 8.3), and with some sensible tuning settings for the hardware used? It will be useful to get some blind tests with more sensible settings. http://monetdb.cwi.nl/projects/monetdb//SQL/Benchmark/TPCH/ Multiple runs from different people/different hardware is useful since they help to iron-out differences in hardware and test methodology. So don't worry if you see somebody else doing this also.
