The other way of providing explicit type information is to create an
object that extends PGobject. Something like:

import java.util.Date;
import java.text.SimpleDateFormat;
import org.postgresql.util.PGobject;

class MyDateWrapper extends PGobject {

public MyDateWrapper(java.util.Date d) {
setType("date");
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd");
setValue(df.format(d));
}
}

Then call PreparedStatement.setObject with an instance of MyDateWrapper.
