数据库管理系统PostgreSQL 8.4 正式发布

时间:2009-07-02  来源:linux论坛

PostgreSQL 是一个自由的对象-关系数据库服务器(数据库管理系统),它在灵活的BSD-风格许可证下发行。它在其他开放源代码数据库系统(比如 MySQL 和 Firebird),和专有系统比如Oracle、Sybase、IBM 的 DB2 和 Microsoft SQL Server之外,为用户又提供了一种选择。
  • Parallel Database Restore, speeding up recovery from backup up to 8 times
  • Per-Column Permissions, allowing more granular control of sensitive data
  • Per-database Collation Support, making PostgreSQL more useful in multi-lingual environments
  • In-place Upgrades through pg_migrator (beta), enabling upgrades from 8.3 to 8.4 without extensive downtime
  • New Query Monitoring Tools, giving administrators more insight into query activity
  • Greatly Reduced VACUUM Overhead through the Visibility Map
  • New Monitoring Tools for current queries, query load and deadlocks
Version 8.4 also makes data analysis easier through the advancedANSI SQL2003 features of windowing functions, common table expressionsand recursive queries. Enhancements to stored procedures, such asdefault parameters and variadic parameters, make database serverprogramming simpler and more compact. Of course, there are alsoperformance improvements included in this version.

Download version 8.4 today and start enjoying using PostgreSQL even more!
