Currently, there is no fixed upstream release for the older branches, but 9.2 is OK. So for jessie, the fix is to move to 9.2 or 9.3, and remove 9.1 and whatever may be left of 8.4. For compiling older versions on jessie (e.g., apt.postgresql.org), the thread discusses workarounds. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
