How about this approach:
Create a temporary table (no constraints)
CREATE TEMP TABLE temptable AS
(SELECT * FROM tablename LIMIT 1);
DELETE FROM temptable;
Copy all data into the temporary table
COPY temptable FROM 'filepath';
Select from the temporary table all items that satisfy the
constraints, insert them into the real table and delete them from
the temporary table:
BEGIN;
INSERT INTO tablename (SELECT * FROM temptable WHERE ...);
DELETE FROM temptable WHERE ...;
COMMIT;
All good data should now be in place. The temporary table should
now contain only those items that do not satisfy the constraints for
the real table.
