Where to find a good reference when choosing a database?

Question

I and two others are working on a project at the university.

In the project we are making a prototype of a MMORPG.

We have decided to use PostgreSQL as our database. The other databases we considered were MS SQL-server and MySQL. Does somebody have a good reference which will justify our choice? (preferably written during the last year)

Answer 1

Someone recently recommended me wikivs.com: MySQL vs. PostgreSQL - it is a quite detailed comparison of those two, and might be of help to you.
