[Zope] Znolk SQL Wizard + Postgres

Hello, According to http://www.zope.org/Members/zwork/Znolk_SQL_Wizard/index_html , Znolk SQL Wizard should work with PostgreSQL. However, after making a PoPy Database Connection, when I initiate the Znolk_SQL wizard, I get : "Warning: There are no database connections. You need to add a Zope database connection in this folder (or in a folder above) before you can use this wizard. By now, the wizard just recognizes MySQL connections." So, does this product work with postgres or not? Any suggestions will be appreciated.
