我需要做的是将这些数据放入如下所示的视图中：
当然可以。2顺序可能不是完全的顺序。3如果你想改变顺序，可以使用order by clause。
设置测试：

begin;
create temp table call(log_Timestamp timestamp,Agent text,  State text);
insert into call values
('2022/11/10 05:00:01',     'Steve'     ,'In Call')
,('2022/11/10 06:00:01',    'Steve'     ,'Waiting')
,('2022/11/10 05:00:01',    'Jack'  ,'In Call')
,('2022/11/10 05:30:01',    'Jack'  ,'Waiting')
,('2022/11/10 07:00:01',    'Steve'     ,'In Call');
commit;

查询：

CREATE VIEW call_view AS
WITH cte AS (
    SELECT
        c1.log_Timestamp AS start,
        lead(c1.log_Timestamp) OVER (PARTITION BY Agent ORDER BY log_Timestamp),
        EXTRACT(EPOCH FROM (lead(c1.log_Timestamp) OVER (PARTITION BY Agent ORDER BY log_Timestamp) - c1.log_Timestamp)),
        Agent,
        state
    FROM CALL c1 ORDER BY Agent,
    log_Timestamp
)
SELECT
    *
FROM
    cte
WHERE
    lead IS NOT NULL;
