Thanks, Hiroshi. We were able to resolve the issue.
After we generated the MyLog we found in the log that the problem was that the odbc user did not have permission to
accessthe large object. Apparently in Postgres 8.4 and lower, all large objects in pg_largeobject were created without
anyowner. When we upgraded the database to 9.1, all large objects were allocated the superuser "postgres" as owner.
Henceodbc applications could not retrieve stored images. Newly inserted images could be retrieved, presumably because
theywere created with the odbc user as owner.
So, we ran a grant select, update command on all the large objects in pg_largeobjects and thereafter were able to
retrieveall stored images through the odbc application.

"detachingprocess". Apart from that I don't see any other log file apart from the one which I posted earlier and which
wasa file that we directed the "tracing" option in ODBC to write to. Can you let me know how to produce the Mylog file
andI shall try it it out.

Please turn on the "MyLog (C:\\mylog_xxxx.log)" DataSource option using
DataSource Administrator
or
add debug=1; to your connection string.
