The machine I am writing from is openSUSE 13.2, but I install Postgres
from source, so I have not actually used the repo versions. That being
said, what I see is they are coming from different repos, the first from
openSUSE-13.2-Oss and the second from openSUSE-13.2-Update. Also look at
the installed sizes for the first 83 B and 3.9 MiB for the second. I
would say the first is just the placeholder package and the second is
the package that represents the most recent version of that placeholder.

What do you see in psql when you do select version()
