```plaintext
--[params]
-- string :username
-- int :min_days = 10

WITH consecutive_visits AS (
  SELECT user_id,
       visited_at,
       -- The value of s will be the same for each group of consecutive days
       visited_at - (DENSE_RANK() OVER (PARTITION BY user_id ORDER BY visited_at))::int s
    FROM user_visits
    WHERE user_id = (SELECT id FROM users WHERE username = :username)
)

SELECT
MIN(visited_at) period_start,
COUNT(*) AS consecutive_days,
MAX(visited_at) period_end
FROM consecutive_visits
GROUP BY user_id, s
HAVING COUNT(*) >= :min_days
ORDER BY period_start DESC

```

I tried with [safe mode](https://meta.discourse.org/t/53504?silent=true) on (official plugins only) and have the same issue.
