I am trying to get only date without time in postgres from the following statement:

select current_date - date_trunc('day',interval '1 month');

But returns me that:

2023-02-07 00:00:00

What could be going wrong here. I see that date_trunc function returns timestamp and intervals cannot be cast to date type:

select current_date - interval '1 month'::date;

>Solution :

You should be able to place the interval expression into a closure, and then cast that:

select (current_date - interval '1 month')::date;  -- 2023-02-07
