Hi guys, thought some of you may be interested:

05-09-2000 - PostgreSQL Global Development Group Releases v7.0 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. 

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: ftp://ftp.postgresql.org/pub/v7.0
