I just installed and tested postgresql-9.4.1, from the debian wheezy packages built and maintained by postgres, and available from their aptable repo of it.
I already had aolserver-4.5.1 running, so I altered my config file to select the 9.4.1 postgres port, and that alteration was all that was needed.
I created the database and made sure plpgsql was installed on it, started aolserver and found I could immediately fill in the installation form, start the installation and in a few minutes it was done and restarted the server.
I was then able to log in, I went to /test and ran all the tests, and they reflect current test-result results: two procs need doc strings, and there is some kind of problem in acs-authentication, in sync_snapshot.
Just like in postgres-9.1.
Are there other things I should test?
