As far as I know, that is not correct. At least if the documentation is
correct:

"You can use a single Statement instance as many times as you want. You
could create one as soon as you open the connection and use it for the
connection's lifetime. But you have to remember that only one ResultSet can
exist per Statement or PreparedStatement at a given time."
(http://www.postgresql.org/idocs/index.php?jdbc-query.html)

So it's not 1 connection -> 1 resultset at a time, but 1 statement -> 1
resultset at a time. I would recommend reading the rest of the documention
about JDBC (especially section 8.3.1)
