From the documentation
(http://jdbc.postgresql.org/documentation/80/query.html#query-with-cursor)
"By default the driver collects all the results for the query at once. This
can be inconvenient for large data sets so the JDBC driver provides a means
of basing a ResultSet on a database cursor and only fetching a small number
of rows.
..."
With a cursor you fetch rows by pieces. It is well explained in the
documentation.
