回复：RE: BUG #19464: Server crash (SIGABRT) with UPDATE containing multiple multi-column assignments

Hi Developer, 

Thanks for the reply. I have verified this on PG 14.22 and can confirm that the issue is not reproducible on 14.22—it returns the expected error:
ERROR: multiple assignments to same column "a"

Best regards,
Chunling

Dear Chunling,

Thanks for reporting issues.

&gt; This issue could not be reproduced with the latest version, but we can
&gt; easily reproduced&nbsp; by&nbsp; PostgreSQL 14devel. I am submitting this report for
&gt; official confirmation.

To confirm, can it happen on the latest PG14 (14.22)? It's the old development
version which should not be used. Same things can be said for other reports.

Best regards,
