It's not clear to me whether your error is during COPY or afterwards.
If it is during COPY, edit your textfile and assign unique values to
each row.
If it is afterwards, use
SELECT setval('sequence_name', SELECT max(serial_field) FROM table);
to set the sequence value. (You probably have to be running 7.1 to use
a sub-select like that.)
