The array support in JDBC is imo nothing better than horrible. However,
the way to go is:
Connection c = getConnection();
Array arr = c.createArrayOf("text", email);

PreparedStatement p = c.prepareStatement(...);
p.setArray(index, arr);

Also notice, that there is no nice way to test array data in frameworks
like DBUnit and others.
