COPY Question

I'm trying to load a table from a flat file using the copy command from
within PG.

Table:
+----------------------------------+----------------------------------+-------+
| Field | Type |
Length|
+----------------------------------+----------------------------------+-------+
| dup_id | int4 not null default nextval('"
| 4 |
| dup_group | int4
| 4 |
| company | varchar()
| 0 |
| matchcode | varchar()
| 0 |
| new_matchcode | varchar()
| 0 |
| gender | char()
| 1 |
| lastnm | varchar()
| 0 |
| firstnm | varchar()
| 0 |
| address | varchar()
| 0 |
| state | char()
| 2 |
| postal_code | varchar()
| 0 |
| life_paid | float4
| 4 |
| life_refund | float4
| 4 |
| ytd_paid | float4
| 4 |
+----------------------------------+----------------------------------+-------+
Index: duplicates_pkey

Copy Command:
copy duplicates from '$SOME_DIRECTORY/cap_dups' using delimiters '|';

Example Record to be inserted:
|7984|cap|99830MTIN557|99830.PBKS557.MRMNT.MBRRST|M|ROBERTS|MATIN|PO BOX
557|AK|99830|0|0|0

Error:
ERROR: Cannot insert a duplicate key into a unique index

As you can see I'm delimiting the fields with a '|' character. You will
also notice that there is no field 1. I was hoping that I could leave
that blank and the sequence automatically fill in the PKEY. Does this
not work?

Any help to why this fail is appreciated.
