\copy command

Hi all, I'm tryingto import data from a file with \copy command. The
file is like this:

000080110;98163 TOSTINE 15 FETTE;KG;4;1;1.48;1.91;910418

000080112;98164 TOSTINE 20 FETTE;KG;4;1;1.93;2.50;910420

000080128;98046 INVERNIZZINA MIGNON;N;4;1;0.83;1.06;910313

000080660;92642 GIRAVOLTE PLAIN GR 200;N;10;1;1.98;2.78;910345

000080661;94460 GIRAVOLTE CORDON BL EU GR 200;N;10;1;1.98;2.78;910347

000080662;92318 GIRAVOLTE POMODORO GR 200;N;10;1;1.98;2.78;910349

000080663;90489 ANNABELLA PZ 2X100 PF;KG;4;1;1.94;2.49;910656

the rows are all similar to these. I've used this command:

billo=> \copy temp_listino from '/home/dario/listino.csv' using
delimiters ';'

where temp_listino description is:

billo=> \d temp_listino
Table "temp_listino"
Column | Type |
Modifiers
-----------+--------------+--------------------------------------------------------------
codart | integer |
descr | text |
um | character(2) |
iva | smallint |
pezzatura | integer |
cessione | numeric(6,2) |
pven | numeric(6,2) |
barcode | integer | not null default
nextval('"temp_listino_barcode_seq"'::text)
Unique keys: temp_listino_barcode_key

but the result is this:

\.
": can't parse "ne 1, pg_atoi: error in "
lost synchronization with server, resetting connection
billo=>

I don't understand why postgres block the import, and why "resetting
connection"? have you some ideas? Thanks all
