Hi,

 

I need to log the start and end time of the procedures in a table. But the start and end time are same. This is how I recreated the issue.

 

create table test_time (time timestamp);

delete from  test_time;

insert into test_time select now();

SELECT pg_sleep(10);

insert into test_time select now();

SELECT pg_sleep(10);

insert into test_time select now();

SELECT pg_sleep(10);

insert into test_time select now();

SELECT pg_sleep(10);

select * from test_time;
