You must give rights to use routines to the users/roles that correspond to applications.
Notes
The query returns a row if there are no user-defined routines that execution privilege is granted to some non-superuser. The query does not consider the routines that are a part of an extension. 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 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.
