[Nexus RM3] Postgresql12 RHEL PROXY

Hi, I’m trying to proxy :
https://download.postgresql.org/pub/repos/yum/12/redhat/rhel-8.3-x86_64/
But, when I’m trying to pull, the repomd.xml and other xml in /repodata differs from the source. So, packages are missing.

Could you help me ?

Thx,

NB : I’m using Nexus RM3 3.31.1-01
