What's the error? How are the NULL values specified in the file?

See the COPY documentation -- COPY has a NULL option that allows
you to specify what string should be interpreted as NULL. Recent
versions also have a CSV option that interprets empty strings as
NULL.

http://www.postgresql.org/docs/8.1/interactive/sql-copy.html

(Use the documentation for whatever version you're running.)
