[Zope] Dynamic SQL problems.

I'm trying to create a dynamic table editor. The idea is you instance this product, give it the database host, user, pass, database name (Postgres in this case, BTW), and table, and you can edit that table via a nifty web interface. The problem is, I don't know what this table's format is beforehand, so I can't realy make any ZSQL methods for inserting new rows. Does anyone know how to work around this? Thanks, DJ.
