PostgreSQL全球开发组今天发布了翘首以盼的8.3版本的第一个beta版本。由于空前数量的新补丁包，这个版本引进了比以前任何一个版本都多新的和改进的功能。当然，更多的新功能意味着8.3需要比以前版本更多的用户来测试，所以我们依靠你们来下载、在你的应用程序的开发版上测试。
新版本的功能有：
- Greatly improved performance consistency, through HOT, Load
Distributed Checkpoint, JIT bgwriter, Asynchronous Commit, and other
features.
- TSearch2 full text search integrated into the core code with improved syntax and ease of adding custom dictionaries.
- SQL:XML syntax.
- Logging to database-loadable CSV files.
- Automated rebuilding of cached plans.
- ENUMs, UUIDs and arrays of complex types.
- GSSAPI and SSPI authentication support.
... and many others. See the release notes for a more complete list of new features.
How soon this beta turns into a release depends on testing by our
community of users. As soon as possible, please help us with community
testing:
