I'm lost in all those acronyms, but am I right in assuming that none of these actually push the planner very hard? We keep on pushing that "PostgreSQL is a lot better than MySQL when it comes to many joins and complex queries" (mostly because the planner is a lot more mature -- does MySQL even keep statistics yet?), but I'm not sure if there are any widely used benchmarks available that actaully excercise that. /* Steinar */ -- Homepage: http://www.sesse.net/
