Antony,
I think you are talking about are two different things. A result set in
jdbc, and a cursor from the backend. Now they could be the same thing if
you used setFetchSize() and the driver was using cursors behind the
scenes.
AFAIK, there is no way to see all the open cursors, however you may be
able to just use ps -auxw | grep post to see your connections.
