New tables don't get permissions of read-only users

We've added a bunch of tables recently that don't appear to have the same access for read-only users. Using \z you can see the projects table has these permissions:

 public | projects                                        | table    | gitlab=arwdDxt/gitlab              +|                   | 
        |                                                 |          | postgres_exporter=r/gitlab         +|                   | 
        |                                                 |          | readonly=r/gitlab                  +|                   | 
        |                                                 |          | gitlab_geo_fdw=r/gitlab             |                   | 

But new tables such as project_repository_states don't have this:

 public | project_repository_states                       | table    |                                     |                   | 
 public | project_repository_states_id_seq                | sequence |                                     |                   | 

I'm wondering if:

1. We need to add some configuration in PostgreSQL to make these tables inherit these values.
2. If not, do we need to grant privileges to each of the users via omnibus or Chef periodically
