Hello there: I am trying to move one of our databases from MS SQL to PostgreSQL and having trouble. One of our table columns is a timestamp type and the contents in MS SQL is nulls. When defined for PostgreSQL, I specifically did not include the "NOT NULL" attribute to this column, but when we issue an INSERT with the null, it fails with an error indicating that nulls are not allowed. What can I do to either get the timestamp data type to permit null values or to redefine my column to accept a timestamp-like type and nulls. Thanks, -- William L. James I/NET, Inc.
