>Description:

After upgrading our test postgresql server, the databases didn't
come back online because of the dreaded shared memory problem.

Checking /etc/sysctl.conf, we saw it was reverted during the upgrade
of the system.

>How-To-Repeat:

- make modifications to /etc/sysctl.conf
- upgrade to 6.0 via the binary upgrade
- check /etc/sysctl.conf

>Fix:
