Ha ha that's just the reverse that should happen.
PGDG is claiming 100% ABI compatibility, which has been proved here that's not the case and all this bug is about this.
If you don't care, me neither, we detected that, we reported it, you decide.
As an editor POV we certainly don't want to build from 3rd parties, except when customer are paying for that specific.
So for us the situation is clear, before the symbol version was introduced in Fedora/Rhel our customer were able to use transparently as the software didn't complain pgdg repository at their convenience.
Now that system libraries are build with symbol version, and our lib depend on those to be present due the build itself, the pgdg might be usable but without any warranties. And we advertise people to better stick to module proposed by the OS editors.
I'm not yet sure what kind of impact those symbol check will have for any software build against system libs in Fedora/Redhat and then used with pgdg lib. I guess the same warning will be emitted each time.
Regards.
