A Smalltalk driver has been developed for PostgreSQL. It consists of two libraries, the driver library is implemented in terms of PostgreSQL interface concepts (message etc.), and the second library is a mapping of the driver library to the ViaualWorks EXDI (think of JDBC) interface. I've included a couple of example of the libraries being used below. What steps need to be taken to get these Smalltalk libraries listed on the PostgreSQL web site? Thanks.
