Appimage use PostgreSQL from host?

I am thinking about creating an AppImage of Xpns-It-Cs once I finish creating Debian and RPM packages. (Normally convert a .deb for my appimage.)

The problem is Xpns-It-Cs relies on PostgreSQL already being installed and configured on the host. We just connect to the database server. The user must already have an account within the PostgreSQL instance.

Is this considered acceptable in the AppImage world?
