Do you find that reproducible?
Did you actually get redirected there somehow? That name is never
supposed to show up in an URL, and as long as it doesn't, it shouldn't
be relevant to SAN..
I just test-installed that repo rpm and then also tried to install
postgres from it and it works fine without any complaints from here...
Can you provide the exact commands you used to get the problem?
