> 
> Announce: Release of PyGreSQL version 3.1
> ===============================================
> 
> PyGreSQL v3.1 has been released.
> It is available at: ftp://ftp.druid.net/pub/distrib/PyGreSQL.tgz.  If
> you are running NetBSD, look in the packages directory under databases.
> There is also a package in the FreeBSD ports collection.              
> 
> PostgreSQL is a database system derived from Postgres4.2. It conforms
> to (most of) ANSI SQL and offers many interesting capabilities (C
> dynamic linking for functions or type definition, etc.). This package
> is copyright by the Regents of the University of California, and is
> freely distributable.
> 
> Python is an interpreted programming language. It is object oriented,
> simple to use (light syntax, simple and straightforward statements), and
> has many extensions for building GUIs, interfacing with WWW, etc.  An
> intelligent web  browser (HotJava like) is currently under development
> (November 1995), and this should open programmers many doors. Python is
> copyrighted by Stichting S Mathematisch Centrum, Amsterdam, The
> Netherlands, and is freely distributable.
> 
> PyGreSQL is a python module that interfaces to a PostgreSQL database. It
> embeds the PostgreSQL query library to allow easy use of the powerful
> PostgreSQL features from a Python script.
> 
> This release fixes a few bugs, adds a few minor features and makes a
> few speedups in the code.
> 
> The next release (unless serious bugs are found) will be to match PyGreSQL
> to version 2.0 of Python.
> 
> See the other changes below or in the Changelog file.
> 
> PyGreSQL 2.0 was developed and tested on a NetBSD 1.3_BETA system.  It
> is based on the PyGres95 code written by Pascal Andre,
> andre(at)chimay(dot)via(dot)ecp(dot)fr(dot)  I changed the version to 2.0 and updated the
> code for Python 1.5 and PostgreSQL 6.2.1.  While I was at it I upgraded
> the code to use full ANSI style prototypes and changed the order of
> arguments to connect.  Later versions are fixes and enhancements to that.
> The latest version of PyGreSQL works with Python 1.5.2 and PostgreSQL 7.0.x
> 
> Important changes from PyGreSQL 3.0 to PyGreSQL 3.1
>   - Fix some quoting functions.  In particular handle NULLs better.
>   - Use a method to add primary key information rather than direct
>     manipulation of the class structures.
>   - Break decimal out in _quote (in pg.py) and treat it as float.
>   - Treat timestamp like date for quoting purposes.
>   - Remove a redundant SELECT from the get method speeding it, and insert
>     since it calls get, up a little.
>   - Add test for BOOL type in typecast method to pgdbTypeCache class.
>     (tv(at)beamnet(dot)de)
