services.postgres: fix quoting in the description of superUser

Ma27 · grahamc · commit 165dc670b1f1 · 2017-11-13T17:01:32.000-05:00
`nixos-option` evals the description and the '`' is used to define shell commands. Due to this, the following error appears: ``` $ nixos-option services.postgresql.superUser Value: "root" Default: "root" Description: /run/current-system/sw/bin/nixos-option: line 294: root: command not found /run/current-system/sw/bin/nixos-option: line 294: postgres: command not found NixOS traditionally used as superuser, most other distros use . From 17.09 we also try to follow this standard. Internal since changing this value would lead to breakage while setting up databases. ``` (cherry picked from commit 82062f7)
