Hello all, I just noticed something and I thought I'd ask: When reading large chunks of data in the 7.4 JDBC client I would code something like this: conn.setAutoCommit(false); st.setFetchDirection(ResultSet.FETCH_FORWARD); st.setFetchSize(1000); st.executeQuery("select * from foo"); which would result in queries to the postgresql server like this: DECLARE JDBC_CURS_588 CURSOR FOR select * from foo; fetch forward 1000 from JDBC_CURS_588; with subsequent fetch forward queries being executed as the full result set is pulled in. In the 8.0 driver I don't see this happening. I see only the "select * from foo" query in the postgresql server log. Is the query result still being sent in batch chunks of 1000 rows, but using a different mechanism? Thanks! -- Alan
