You can't use sequences in conjunction with COPY; you have to fill in
the field in your input text file.
If it is a big file, you could use a tool such as awk or perl to write a
value into each line of input. After loading the file, you will need to
set the sequence value:
SELECT setval('sequence_name', last_value);
