Granting and revoking access
Access control is a key aspect of database management. Not all database users have the same needs and goals, from analysts, clerks, data scientists, to data engineers. As a general rule of thumb, write access should never be the default and only be given when necessary.
In the case of our Pitchfork reviews, we don't want all database users to be able to write into the long_reviews view. Instead, the editor should be the only user able to edit this view.
