When I try to query data per month for last year the database always crashes.
Statement:
SELECT time_bucket('1 month', time) AS bucket, max(value)-min(value) AS value
FROM openems_energie_erzeugung
where"time">='2023-01-01'and"time"<='2023-12-31'GROUP BY bucket;
If I change the second time in the where clause to '2023-12-14' the query executes successfully. Change to '2023-12-15' lets the database crash.
