Howdy.

I have an Ubuntu 14.04 LTS, configured with huge pages (4x1GB, disabled transparent) and a later kernel than what ships with 14.04.

root@ff2:~# uname -a
Linux ff2 3.16.7-ckt11-061515+ #1 SMP Mon Jun 15 18:47:13 CDT 2015 x86_64 x86_64 x86_64 GNU/Linux

It had postgresql-9.3 on it and I installed postgresql-9.5 via these steps:

aptitude remove -y postgresql-9.3 
echo "deb http://apt.postgresql.org/pub/repos/apt/ trusty-pgdg main 9.5" > /etc/apt/sources.list.d/postgresql.list
apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7FCC7D46ACCC4CF8
apt-get update
apt-get install -y postgresql-client-9.5 postgresql-common postgresql-9.5

At the end of the install, these were emitted to the screen:

I'm able to connect and I dumped a few default relations.

Is the munmap error of concern? It remains upon rebooting / restarting the server. 

Thanks,
Chris
