Its been 8 months since the last major release of PostgreSQL, and the
PostgreSQL Global Development Group is now proud to announce our next leap
forward with the release of v7.0.

Although there have been alot of changes between v6.5 and v7.0, most of
them have been under-the-hood ... reducing, and in some cases, eliminating
some of the limitations in previous version of PostgreSQL.

There are over 70 bug fixes, over 100 enhancements and over 30 performance
improvements in this new release ... all of which are documented in our
HISTORY file, but some of the more visible changes are:

   Foreign Keys
          Foreign keys are now implemented, with the exception of PARTIAL
          MATCH foreign keys. Many users have been asking for this
          feature, and we are pleased to offer it.
   Optimizer Overhaul
          Continuing on work started a year ago, the optimizer has been
          overhauled, allowing improved query execution and better
          performance with less memory usage.
   Updated psql
          psql, our interactive terminal monitor, has been updated with a
          variety of new features. See the psql manual page for details.
   Upcoming Features
          In 7.1, we plan to have outer joins, storage for very long
          rows, and a write-ahead logging system.

   Date/time datatypes cleaned up
	  We have brought the date/time datatypes into compliance with
	  the SQL standard, replacing the old partially-implemented SQL
	  date/time types with full-featured implementations.  The
	  default display format for date/time data has also changed
	  to be ISO style.  This may create a few compatibility issues
	  for old applications.  [Thomas may want to rewrite this item...]

   Query length limits removed
	  There is no longer any fixed limit on the length of a query
	  string.  (The block-size limit on the length of a stored row
	  still exists, but we hope to fix that in 7.1.)

   Removal of 8-argument limit on index keys and functions
	  The maximum number of keys in an index or arguments to a
	  function is now configurable, with default limit of 16,
	  rather than the old hard-coded limit of 8.

   Sorts and hashes now work for >2GB of data
	  Temporary files can now be split in the same way that oversize
	  relations are, so that data volume is only limited by
	  available disk space and not by OS limits on the size of an
	  individual file.

Also, to facilitate those with unstable or low bandwidth connections, the
PostgreSQL distribution is now available as a complete .tar.gz file, or 5
seperate .tar.gz files, all available at:
