ODBC and Large Objects, FAQ not working

Hi,

I know you've read this all before, as I went through most postings concerning this issue. But I
haven't found a reply that helped me, so I hope I'll get one this way.

I want to hook up Microsoft Access (2000) via ODBC (6.400007) to my PostgreSQL server
(6.5.3, Linux 2.2.10). Everything works fine, but I am having trouble inserting OLE objects into
my database.

I created the "lo" type suggested in the ODBC FAQ and a basic table (CREATE TABLE ole (id
int4, bild lo);) for testing purposes. But when I insert an OLE object, I get the error message
"Couldnt open large object for writing (ERROR #1)".
I attached the corresponding log.

I'd appreciate your help in this matter, as I tried any advice given in earlier postings concerning
problems like this, but nothing would help.

Chris
