Re: "Resend email" gave me a "does not exist" message - Mailing list pgsql-www

I got another of these shortly before: Sun Mar 15 22:24:54 CDT 2020 (Mon Mar 16 03:24:54 UTC 2020)
https://www.postgresql.org/message-id/resend/CAOBaU_Z6WcT8FJfcCMU_Bp%20PTzUpTEY9BfBQE4gbGKpE5wpfwQ@mail.gmail.com
=> Not Found The requested page was not found.

Going "Back", I'm at:
https://www.postgresql.org/message-id/CAOBaU_Z6WcT8FJfcCMU_Bp%2BPTzUpTEY9BfBQE4gbGKpE5wpfwQ%40mail.gmail.com
back again, I get to:
https://www.postgresql.org/message-id/20200118025102.GB230692%40paquier.xyz

Looks like before that, I was at a firefox tab at:
https://www.postgresql.org/list/pgsql-hackers/since/202001180000/
..and I used "control+click" to open new tab.

Also, I'm copying a previous message to which I didn't see a reponse.
