game db

Hello!

I'm currently coding a game, using C++ and OpenGL. I need to store
the game state data into a database, and heard alot of positive
things about PostgreSQL. As this is a game, speed is critical. I'm
going to do alot of writing to the database, but seldom much reading
from it, so I'm mostly interested in write-speeds.

Does anyone have an idea if Postgresql could suit my needs, or should
I look into other databases (mysql for instance) ?

Best regards,
Kenneth Gangstø
