I recently installed psycopg2 - is this the same package you wanted?

If so, Google for "psycopg2-2.0b4-pre4.win32-py2.4.exe", which is a 
pre-bult binary installer (though the version I picked up wasn't able to 
handle mx.datetime objects, this shouldn't be a problem unless you have 
other modules that generate them).

Never used PygreSQL, so can;t help there (though you might try a similar 
trick and Googal for "PygreSQL Windows installer", say).

If you look at

   http://www.holdenweb.com/Python/

you'll find a link to Mike Fletcher's page describing how you can 
install and use the free Microsoft toolchain to compile extension 
modules so they will be compatible wiht the Python installed by the 
Windows installer from python.org.
