Hi,
I have following problem with the ODBC driver or is it the server? I have an
MS Access Database which I want to put into a postgres database to have MS
Access to be only the frontend. That worked fine until I came across an OLE
field.
So I created an lo type in my postgres database as it is described in the
postodbc faq.
Now, when I want to access the lo type field in my postgres database from ms
access then I get an error:
"Socket has been closed"
the postmaster log returns something like this:
indExec: found "/usr/lib/pgsql/bin/postgres" using argv[0]
/usr/lib/pgsql/bin/postmaster: BackendStartup: pid 16319 user postgres db
test socket 5

and the odbc driver log returns this:

I am able to put one object into this field, but i cannot retrieve it. I
have to close ms access and to restart the postmaster then I can read this
object and the everything is down again.
how can i fix this?
thanks for your help
Robert
