Database migration from Access 2000

Dear support team,

I'm trying to migrate an Access 2000 database to
PostgreSQL 7.20.

While migrating a table that doesn't contain any data
the following error message occurs:

An error occured at: 08.10.2002 19:07:01:
94: Ungueltige Verwendung von Null ("Invalid usage of
Null")


The log file says:
