dump data into table with sequence

Given this table:

Table = rechnung_kunde_199805
+----------------------------------+-------------------------------------+-------+
| Field | Type
| Length|
+----------------------------------+-------------------------------------+-------+
| rechnungs_id | int4 default nextval ( 're_id_seq')
| 4 |
| kunden_nr | int4
| 4 |
| stream_name | varchar()
| 40 |
| offset | int4
| 4 |
| length | int4
| 4 |
| datum | date
| 4 |
+----------------------------------+-------------------------------------+-------+

There is a unique index on rechnungs_id and a sequence 're_id_seq'.

I want to insert loads of data into this table -> 'psql DB <
data.sql'
data.sql is like: 'COPY .. FROM stdin;' __data__ \.
and the 'first field == rechnungs_id' in the data is empty (just a tab).

This doesn't work as PG tries to insert NULL as value for rechnungs_id
instead of
using the sequence.

Q: Is there a way to solve that problem other then defining a trigger?
If not:
Q: Can someone give me an example how to define the trigger (and the
procedure?) here?
I have read the docs (+ the contrib stuff), but still don't know exactly
how to
implement that.

regards, Tony
