| Query goal: | You must give privileges to use views to the users/roles that correspond to applications |
| Notes about the query: | The query returns a row if there are less than three views that usage right is granted to some non-superuser. It could be that the user, which corresponds to an application, has some but not all the necessary privileges in the database. In this case the query will give false negative answer. The number in the condition (3) is an example and could be changed. The condition in the query ensures that if the requirement is not fulfilled, then the query returns one row, otherwise it does not return a row. The result is achieved by using a PostgreSQL feature that permits SELECT statements without the FROM clause. |
| Query type: | Problem detection (Each row in the result could represent a flaw in the design) |
| Query reliability: | Medium (Medium number of false-positive results) |
