Description

We allow using zero indexes for elements in array column and returns null by accident.
A simple test case to reproduce:

        Properties props = PropertiesUtil.deepCopy(TEST_PROPERTIES);
        Connection conn = DriverManager.getConnection(getUrl(), props);
        conn.createStatement().execute("create table A(ID INTEGER PRIMARY KEY, array_id VARCHAR[])");
        conn.createStatement().execute("upsert into A values (1, ARRAY['test','test2','test3'])");
        conn.commit();
        ResultSet rs = conn.createStatement().executeQuery("select array_id[0], array_id[1] from A");
        while(rs.next()) {
            System.out.println(rs.getString(1));
            System.out.println(rs.getString(2));

        }

The result for 4.x branches would be

{null, 'test'}

and it would fail with an exception for 5.x.
