Here's the smaller version of the query that reproduces it. The window
function isn't necessary.
```
WITH "simple_data" AS (
SELECT "user_id",
"value",
"date"
FROM "events_table"
WHERE "account_id" = 'acct_sample123'
LIMIT 500
)
SELECT "date",
SUM(
CASE
WHEN "value" > 0 THEN 1
ELSE 0
END
) AS "count_positive"
FROM "simple_data"
GROUP BY 1
LIMIT 10
```
Explain plan
```
