The question for me is how do you portably use cursors so that you can work
with Oracle and PG seamlessly?  I presume there might be some (hopefully)
slight variations, like there are with BLOBs, but it would be nice if using
cursors was standardized enough to make it using standard JDBC.

It seems that the issues are with defining a cursor, executing it, fetching
against it, then release it when done.  Is there a standard way to do this?
Any examples?

Thanks,
