MySQL vs. PostgreSQL comparison

I was looking for some clear and professional comparison between MS SQL Server and MySQL, so I can figure out how much until MySQL will start to be user by professionals. I was only able to find a very well organized comparison between MySQL and PostgreSQL. Actually this is more revealing than the comparison I was looking for, because MySQL is still far behind, probable in a different category than MS SQL Server, considering the features implemented.
