Sort of. The Postgres packages appear to be from CentOS Stream:


https://rpmfind.net/linux/RPM/centos-stream/9/appstream/x86_64/postgresql-private-libs-15.2-1.module_el9+264+92dde3f0.x86_64.html

I don't have RHEL 9 handy at the moment to check what its repo has for 
Postgres packages.

But the OP clearly stated they were running Amazon Linux on the primary, 
so perhaps these Postgres packages were downloaded from somewhere that 
does not match the aforementioned distro -- yet another potential issue 
for various reasons.

Or perhaps they got their own distro wrong ¯\_(ツ)_/¯
