Missing package for Red Hat on ppc64le

Hello,

we have huge DWH based on PostgreSQL 13. It runs on IBM PowerPC (ppc64le) with Red Hat Enterprise 7. Now we would like to update OS to version 9 and also PostgreSQL to version 15 or 16. Unfortunately for ppc64le with Red Hat Enterprise 9 does not exists any available PostgreSQL release.

I would like to ask if it is possible to create it for this combination? If it is, approximately when will it be available?

Thank you very much in advance
