That solved the confusion. I wasn't aware that gadfly support has been removed from later versions of Zope.

We certainly wanted to migrate to PostgreSQL due to other problems with gadfly. At present, the website is being used continuously and I see no other way of fixing the issue quickly other than migrating to a higher version of Python. I am not sure how long the migration to PostgreSQL would take as I could not find any method to import a gadfly database into postgres.I am afraid I will have to export data from all the tables and import them back into Postgres and change the scripts using the connection. -Vimal
