If you look through this mailing list, the PostgreSQL website, and Google reviews of PostgreSQL, I think you will gain a very positive appreciation of PostgreSQL. It is stable, robust, and well-supported. It is being used in many mission-critical applications. Most recently, I've seen mention that it is being used by the Wisconsin court of appeals and I believe I saw a European government had selected it for their census data (perhaps the Netherlands?).
