Thanks a lot, Kris.
For clarification, is this then a JDBC patch work that need to be done to enable scrollability feature in the ResultSet via CallableStatement?
Domo arigato!

You've sent this to the list owner address, please send all non list
administration questions to pgsql-jdbc@postgresql.org.
It wouldn't be hard to allow scrolling, we just need to get that
scrolling flag to the ResultSet. Allowing updates is not going to
happen without some significant work. The backend would need to support
updatable cursors because the driver has no idea what the cursor is
actually accessing so it cannot issue updates as it does for regular
ResultSets.
I'm travelling at the moment, but will be back home next week and will
hopefully look at this and all the other pending JDBC patches/issues.
