I'm doing icustay_times.sql in a postgres database

\i icustay_times.sql
我在导入icustay_times.sql时出现一个报错
[SQL] Query icustay_times start
[ERR] 错误: 由于语句执行超时，正在取消查询命令

DROP TABLE IF EXISTS icustay_times; CREATE TABLE icustay_times AS
-- create a table which has fuzzy boundaries on hospital admission
-- involves first creating a lag/lead version of disch/admit time
-- get first/last heart rate measurement during hospitalization for each stay_id
WITH t1 AS (
SELECT ce.stay_id
, MIN(charttime) AS intime_hr
, MAX(charttime) AS outtime_hr
FROM mimiciv_icu.chartevents ce
-- only look at heart rate
WHERE ce.itemid = 220045
GROUP BY ce.stay_id
)

-- add in subject_id/hadm_id
SELECT
ie.subject_id, ie.hadm_id, ie.stay_id
, t1.intime_hr
, t1.outtime_hr
FROM mimiciv_icu.icustays ie
LEFT JOIN t1
ON ie.stay_id = t1.stay_id;

经过分析是group by导致查询过慢，请问该如何优化或者怎么样做才能导入成功
After analysis, the execution is too slow due to group by, how to optimize or how to import successfully?
