I'm not sure what you mean with "shared namespace's owner".

This is my dovecot-sql.conf.ext

iterate_query = SELECT email AS user FROM users

password_query = \
    SELECT email, password, login , concat('*:bytes=', quota) AS userdb_quota_rule \
    FROM users \
    WHERE email = '%u' AND login = 'active'

user_query = SELECT \
    `home`, concat('*:bytes=', quota) AS quota_rule \
    FROM `users` \
    WHERE `email` = '%u'

Thanks for looking into it. I'll test this and let you know.
