I believe Access will give this mesage when the primary key of a record has
been  modified. I think the text type is mapped to memo fields which Access
cannot use as a primary key. If  a table does not have a primary key it
will use the fields of the original record as sort of combined key to
identify the record. If any field is changed this will then generate the
message. It may be that if you set the Row Versioning flag in the postgres
ODBC driver this may resolve the problem.
