PostGreSQL 8.0 is a pretty impressive product that doesn’t get the attention of MySQL, but really should. It’s a full-featured relational database engine with most of the competitive features of the big boys: triggers, RI, procedures, etc. In the 8.0 product, the press release claims the most features in any dot-zero release of PostGreSQL. Notable is a native Windows port for better introduction into monoculture shops.
