a bit OT... I use Oracle (yep!) everyday. It's a very solid database. However, somehow, I read about postgresql every day, on planet.postgres and in some other web sources (and I use it a bit in side projects). All the qualities of Postgres aside, what sets it apart is that its develeopement unfold under my eyes and there'd hardly one week without an interesting news or comment or blog post, etc (from non marketing people). That's the opposite of Oracle for which I hear news when the databse team in my job upgrades it, ie once every three years (or when I read some advertisement). That makes Oracle dull. That heighten the trust I have into it.
One may argue that's just the way the web is, but nonetheless, it gives me that warm feeling...
