I'm using the lo type defined in the FAQ at:

http://gborg.postgresql.org/project/psqlodbc/faq/faq.php?faq_id=52

I'm using Borland C++ 6 but the problem seems to be coming from the 
driver as when I enabled logging, I get messages like:
conn=67191248, query='COMMIT'
The 2th item was truncated
The buffer size = 32769 and the value is '1040924'

even when I modified Max LongVarChar in the data source.

If the image size is less than 32769, it works but anything larger than 
that will be truncated on the retrieval only.
Best regards,
Xavier
