Zammad password default postgresql

Hi somebody, can tell me what’ the password by default of postgresql i installed zammad with debian package and the installation was automactly; i see that the password is by default blank but if i change this password for access remotly for monitoring the services, this change will affect to the system?

There is no default password for the postgresql user. In fact, our creation script configure the user to use sockets instead of password authentication.

You technically can set a password of your choice.
If you ensure that socket and password authentication works, this will also not be of an issue for Zammad.
