Where are archived non-free repos? - Mailing list pgsql-pkg-yum

Hi Devrim,

I was moving our v13 repos to point to yum-archive.postgresql.org, but
currently at this URL, there exists only archives for v10 and v11.

https://yum-archive.postgresql.org/non-free/

Whereas the main URL has what I thought would be archived versions v12, and v13:

https://ftp.postgresql.org/pub/repos/yum/non-free/

Do we never archive the non-free repo any longer?

Thanks.
Greg.
