A few years ago, I released an alternate PostgreSQL interface for Squeak. 
Recently, Leonardo Cecchi (l.cecchi at mind-informatica.com) greatly improved 
upon the code by fixing some bugs, adding SmalltalkX compatability, and 
creating SUnit tests.

"You will notice that BeOS has taken the best parts from all the major
operating systems and made them its own. We've got the power of the Unix
command line, the ease of use of the Macintosh interface, and Minesweeper
from Windows." -- Tyler Riti
