This cartridge requires phpPgAdmin
5.0.x to be installed on the node on which your application is running.
This will be installed when this cartridge is, but this is not the case with OpenShift Online as of this writing.
If you are running your own installation of Origin, then I assume you know what you are doing and that you can make use of this cartridge.
The phppgadmin
cartridge provides phpPgAdmin on OpenShift.
Add this cartridge to an application that already has PostgreSQL:
rhc cartridge add phppgadmin-5.0 -a APP
Admin user name and password will be displayed.
And access /phppgadmin
on your application's site and log in with
the credentials given above.
