Dears, This issue has been pending for several months without any response. And this problem still exists in the latest minor versions of PG 12 and PG 13.
I believe that the fix in this patch is helpful. The patch has been submitted https://commitfest.postgresql.org/43/4393/ . Anyone who is interested in this issue can help with the review. Regards!
