Summary: Bug with datatype lo and server side cursor

Initial Comment:
Since the latest version of our application we switched from clientside to serverside cursor. Everything works fine except for tables that have a lo field. Since we use serverside cursors we can't post any data to the table in the lo field. It seems like the ODBC driver is generating the wrong query and is inserting the blob content directly, without quoting, into the update query.

We have the following configuration:
PostgreSQL version:
PostgreSQL 8.3.7 on Debian 4.3.2-1.1
ODBC driver:
PostgreSQL Unicode 8.03.04.00 (also tested with version 8.04.01.00)

I'm sorry. It was indeed the Global option that I used. In
the new file that I have uploaded you will find the output
with the datasource option enabled.

Unfortunately I can see only out of connection log.
Maybe you are turning on the Global option.
Please turn on the Datasource option as well.
