Dunno why you are getting downvoted. MySQL is such a poor database that is always leads to hacks. The people who use MySQL almost always get burnt by something and figure all DBs are like that. Then people who have never worked with non-toy databases assume all databases are like MySQL and dismiss the whole field, which is a complete shame.

The fact is, a real database system like PostgreSQL is one of the coolest, most underutilized tools developers have in your toolbox. Good databases can do so much cool shit to help you. It is amazing how well a good database system can take your weird crazy query and return something in mere milliseconds.
