te answer!

I have this table:

aif_test=# \d sbox;
              Table "public.sbox"
  Column |          Type          | Modifiers
--------+------------------------+-----------
  id     | character varying(255) | not null
  data   | lo                     |
Indexes:
     "sbox_pkey" PRIMARY KEY, btree (id)


And trying to insert a binary file which I show only the first lines:

When runing a simple insert I get:

[postgres@dbfactura01dmz  /tmp]$ psql -d aif_test -U aif <
subida_postgres_copys_sbox.sql
Password for user aif:
ERROR:  invalid input syntax for type oid:

sql script:
[postgres@dbfactura01dmz  /tmp]$ more subida_postgres_copys_sbox.sql
COPY sbox FROM '/tmp/TXT/SBOX.txt' WITH DELIMITER '|' NULL '';

I am not able to insert a simple binary text into a "lo" type column!!!
Read on the doc but it should work thoug. Any help please??

I think the type you are looking for is bytea:

http://www.postgresql.org/docs/9.0/interactive/datatype-binary.html

If you really want to use large objects(lo) see here:
