  Log:
  Welcome to PostgreSQL 8.1.
  
  The new release includes performance improvements and advanced SQL
  features which will support bigger data warehouses, higher-volume
  transaction processing, and more complex distributed enterprise
  software.
  
  Major new features in this release include:
  
        Roles:
             PostgreSQL now supports database roles, which simplify the
             management of large numbers of users with complex
             overlapping database rights.
  
        IN/OUT Parameters:
             PostgreSQL functions now support IN, OUT and INOUT
             parameters, which substantially improves support of complex
             business logic for J2EE and .NET applications.
  
        Two-Phase Commit (2PC):
             Long in demand for WAN applications and heterogeneous data
             centers using PostgreSQL, this feature allows
             ACID-compliant transactions across widely separated
             servers.
  
  Some Performance Enhancements found in this release include:
  
        Improved Multiprocessor (SMP) Performance:
             The buffer manager for 8.1 has been enhanced to scale almost
             linearly with the number of processors, leading to significant
             performance gains on 8-way, 16-way, dual-core, and multi-core
             CPU servers.
  
        Bitmap Scan:
             Indexes will be dynamically converted to bitmaps in memory when
             appropriate, giving up to twenty times faster index performance
             on complex queries against very large tables.
  
        Table Partitioning:
             The query planner is now able to avoid scanning whole sections
             of a large table using a technique known as Constraint
             Exclusion.
  
         Shared Row Locking:
             PostgreSQL's "better than row-level locking" now supports even
             higher levels of concurrency through the addition of shared
             row locks for foreign keys.
