I have a simple task: bulk insert csv file to the table. The .ctl file is

TYPE = CSV                            # Input file type
ESCAPE = \                            # Escape character for Quoting
DELIMITER = ","                       # Delimiter
PARSE_BADFILE = "/home/USERNAME/bulkload.bad"
LOGFILE = "/home/USERNAME/bulkload.log"
WRITER = BUFFERED
CHECK_CONSTRAINTS = YES
PARSE_ERRORS = 0

I'm importing csv file of approximately 6MB size. The import proceeds for 2-3 minutes, eats all free space (14 GB on main partition) and ends up in this error:

2012-10-28 12:13:22 UTC ERROR:  could not extend file "base/383631/709460.1": wrote only 4096 of 8192 bytes at block 177462
2012-10-28 12:13:22 UTC HINT:  Check free disk space.
2012-10-28 12:13:22 UTC STATEMENT:  SELECT * FROM pg_bulkload($1)

The table I'm inserting into have 74732120 rows already.

UPDATE:
The CSV file is 4-6 MB size, 150-300k rows in average.

UPDATE 2: the table definition is

id               | integer                  | not null default   nextval('shops_offer_id_seq'::regclass)  
is_trashed       | boolean                  | not null
price            | double precision         | not null
availability     | double precision         | 
description      | text                     | 
identificator_id | character varying(148)   | not null
shop_id          | integer                  | not null
date             | timestamp with time zone | not null
transaction_id   | integer                  | not null
Indexes:
"shops_offer_pkey" PRIMARY KEY, btree (id)
"shops_offer_identificator_id" btree (identificator_id)
"shops_offer_identificator_id_like" btree (identificator_id varchar_pattern_ops)
"shops_offer_is_trashed_idx" btree (is_trashed)
"shops_offer_shop_id" btree (shop_id)
"shops_offer_transaction_id" btree (transaction_id)
Foreign-key constraints:
"shops_offer_identificator_id_fkey" FOREIGN KEY (identificator_id) REFERENCES products_identificator(id) DEFERRABLE INITIALLY DEFERRED
"shops_offer_shop_id_fkey" FOREIGN KEY (shop_id) REFERENCES shops_shopcore(id) DEFERRABLE INITIALLY DEFERRED
"shops_offer_transaction_id_fkey" FOREIGN KEY (transaction_id) REFERENCES shops_importtransaction(id) DEFERRABLE INITIALLY DEFERRED

The row sample of CSV is

201298602,False,29.2,1.0,"","5000000000500000000037",965,"2012-11-05 11:10:23",1269570

Last time the file was 7.5MB.
We solved the issue for now by increasing disk space, but the problem persists.

Please include the table definition. And, if possible, try uploading the same CSV with COPY. –  dezso Nov 2 '12 at 20:17
    
... and how big is the CSV? Rows (use wc -l if in doubt), columns, data types, and on-disk file size? –  Craig Ringer Nov 3 '12 at 1:50

Have you tried COPY? –  dezso Nov 5 '12 at 6:34
    
Nah, sorry, no possibility for now. I'll try it later. –  Mudblood Nov 5 '12 at 8:28
