PostgreSQL version: 12.8
Operating system:   Ubuntu
Description:

In the previous version 12.6, the date cast is handled without errors, but
in version 12.8 this generates an error
SELECT '20.08.2021'::date

ERROR:  date/time field value out of range: "20.08.2021"
LINE 1: SELECT '20.08.2021'::date
               ^
HINT:  Perhaps you need a different "datestyle" setting.

I know that you can use to_date ('20 .08.2021 ',' DD.MM.YYYY '), but this is
less convenient
