The PostgreSQL Global Development Group has released version 8.4, 
continuing the rapid development of the world's most advanced open 
source database.  This release contains an abundance of enhancements to 
make administering, querying, and programming of PostgreSQL databases 
easier than ever before.  Our development team has spent 16 months 
adding over two hundred improvements to all aspects of database 
functionality, helping every PostgreSQL user in small or large ways.

Many of the changes in PostgreSQL 8.4 are new or improved administration 
and 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.
