You think the CTO or CFO in most companies have any clue what ACID

Ok, how many companies bank their entire business on PostgreSQL but
don't have a support contract? Sure, the odds of something going
wrong are small and the community generally does a great job at
support, but if an hour of downtime will cost you thousands of
dollars, doesn't it make sense to spend a couple grand on a support
contract?

You can certainly make MySQL as robust as PostgreSQL; it's just
harder to do so.
