[DRE-maint] Bug#859200: gitlab: Upgrading postgres and gitlab together fails

[Benjamin Drung]

Package: gitlab
Version: 8.13.11+dfsg-8
Severity: grave
Justification: renders package unusable

Hi,

I ran an "apt upgrade" which wanted to install gitlab 8.13.11+dfsg-8 and
upgrade postgres. The upgrade of gitlab fails because postgres was not
running. So you probably have to pre-depend on postgres if you rely on
having postgres running while postinst is running.

Relevant apt output:
