monitoring tools and commands. Each user has their own favorite features which will make day-to-day work with PostgreSQL easier and more productive for them. Among the most popular enhancements are: * 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 advanced ANSI SQL2003 features of windowing functions, common table expressions and recursive queries. Enhancements to stored procedures, such as default parameters and variadic parameters, make database server programming simpler and more compact. Of course, there are also performance improvements included in this version.

PostgreSQL is a robust, next-generation, Object-Relational DBMS (ORDBMS),
|
|
derived from the Berkeley Postgres database management system. While
|
|
PostgreSQL retains the powerful object-relational data model, rich data types
|
|
and easy extensibility of Postgres, it replaces the PostQuel query language
|
|
with an extended subset of SQL.
|
|
|
|
PostgreSQL is free and the complete source is available.
|
|
|
|
This package contains the database client programs.
