Nope, there are none. Which is expected, 'cause user_email was
declared not null:

rdw=# select * from reg_user where user_email is null;
 user_id | user_email | user_passwd | user_active | user_allow_pauth | user_full_name | user_pseudonym | user_who
---------+------------+-------------+-------------+------------------+----------------+----------------+----------
(0 rows)

rdw=# select * from broken where user_email is null;
 user_email
------------
(0 rows)

And the locale is probably OK, too. I tried dumping the table in
question and passing it through sort/uniq. It worked OK, unlike GROUP BY in
Postgres.
