[Zope] PostgreSQL, INSERT and new OID

Hello. I am just learning Zope. I have a few projects that I created using Apache and FastCGI, but Zope has caught my eye. In learning Zope, I came across a stumbling block, and that is how to retrieve the OID that an INSERT query will create when using Postgre. In previous projects, when a new record (let's say a contact) was created, if the INSERT was successful, the user was automatically refreshed to the newly created record. (If not, an error was displayed). I can not figure out how to get the OID that is returned by issuing a INSERT SQL statement. Can anyone help me out with this one? Thanks! Jeremy - jeremy@cowgar.com
