I'm just starting to make use your service and familiarize with it. So far, I really like it a lot! Especially that everything is described briefly but yet sufficient to not get stuck.
But the one thing which I do not get so far: Why is it that even the Free Beginner accounts can have a MySQL DB for free, but for PostgreSQL, you have to pay? Based on what I know both are completely free and based on my experience, neither it is more complex to maintain a PostgreSQL system compared to a MySQL one, nor is PostgreSQL more resource - hungry.
