Postgres - how to skip 'sequence' columns

Is it possible to skip column(s) in the target table when using
pg_copy_from? When I tried to bulk insert some data from a csv
file by way of pg_copy_from I received the error "Warning:
pg_copy_from() [function.pg-copy-from]: Copy command failed:
ERROR: permission denied for relation xyz", pretty much as I
expected since things look like:

CREATE SEQUENCE xyz;
CREATE TABLE some_table (
  id int NOT NULL PRIMARY KEY DEFAULT nextval('xyz')
...
(i.e. the first column is automatically populated by the db itself).

The csv file contains only data for the second and subsequent
columns, so anyway needs to "hop right" one column.
