Re: Question on cast string to date - Mailing list pgsql-general

Hi,

    I test the following SQL in pg15dev (seems same behavior as the previous version).

    select '2020701'::date;

    date
   ------------
    0202-07-01
   (1 row)

   At the first glance, the result seems quite strange.

   Go through the code, postgres use date_in to do the cast, and firstly use last 2 chars to

   get the day, and the 2 chars to get the month, and all remaining chars as year.

   The question here is: should we throw error for such input? Or what standard postgres is

   using to cast such kind of string?

Thanks.
