cubicweb #615353 db-restore is not clear on which passwords it is asking for [open]

When doing a db-restore we get a prompt for a password, twice or thrice and two problems are confusion :

  • the user is not sure which password is being asked (postgres or cubicweb admin password)
  • when prompted again, the user thinks he got the wrong password when the connection worked
