Well...my response is considerably different than Roberto's.
Consider that for years the MySQL folks sneered at, belittled, and lied about the value of the ACID test, and transactions (which are part and parcel to it).
Now MySQL finds itself in the interesting position of offering interfaces to two different back ends that claim to pass the ACID test.
If the MySQL statements about ACIDity were true, why are there now two ACID backends and only one flat-file back end?
Maybe MySQL was wrong.
Armed with this amazing backpedaling (which has been thoroughly forgiven by fans making those in love with Philip look like a bunch of pikers), certainly it is time to point out that their idiocy in regard to foreign keys and other SQL requirements are equally out of whack, mindless, stupid, and harmful to small children who try to build websites on MySQL?
By allying themselves with two ACID backends, they've essentially stabbed themselves in the back as far as credibility.
I don't care enough to chase after them. But the PG folks and others who get a clue (to some degree, the PG crew misses amazing clues as well at times) and want to make money supporting their more robust RDBMS engines should fling past statements by Monty et al about how horrible ACID compliancy is right in his face.
