You don't "associate" a role to a database, you create a role *in* the database where the role is going to be used.

You've got a problem here because you already have some permission defined that refers to a *user* named UTENTI_GO.

Use a different identifier for the role, one that is not the same as a user name.

A role exists ONLY in the database it is created in - unlike users, that exist across the whole server. A ROLE is a mechanism for packaging sets of permissions.

1. Create the role (unique, and not the same as any user name)
2. Grant permissions to the role.
3. Grant the role to each user that needs to have that package of permissions.
