I don't think so. The Javadoc for Statement says:

"By default, only one ResultSet object per Statement object can be open at
the same time"

To me, this suggests that some db's may allow multiple ResultSets per
Statement but that such extensions would be non-portable. Looking at the
source for AbstactJdbc1Statement, it has

protected java.sql.ResultSet result = null;

So it looks like PG has the one ResultSet to one Statement implementation.
