ehxz

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:

    * Test installing & configuring the new version.
    * Try out the new features, alone or in combination.
    * Test porting your old applications.
    * Test integration with drivers and other database tools.
    * Run performance tests on the new database.
    * If you are a Windows developer, try compiling using our new Visual C++ support.
