I know that MySQL does not have all the features of Postgres. I simply meant that, for ages, there have been all sorts of benchmarks floating around purporting to show that MySQL is faster than Postgres. None of these have ever taken into account the transaction overhead that Postgres automatically incurs. With InnoDB transactions, MySQL seems to have the same sort of transactional overhead. So, a real comparison can be made. Yes, all sort of other nice features will be missing. No-one needs to convince me of the benefits of Postgres. But if MySQL _really_ has transactions now, and they really scale and all that, then we may have something to learn from it (well, ok, others may have something to learn from it. I can barely write 'Hello World' in C, so I'm not going to be much use as a code contributor). And since InnoDB and MySQL are both GPL'd, one would be able to examine the source for bright ideas, if it turns out that MySQL+InnoDB is blazing fast with (say) 50 concurrent users. Anyway, it was just a suggestion. Sorry I brought it up, since it has the potential to spark another holy war.
