• Improve and extend the base implementation of Role-based access control (RBAC):

  • Add the has_table_privilege access control function, which allows a role to query if it has privileges on a specific relation:

    SELECT has_table_privilege('marta','auction_house','select');
    
    has_table_privilege
    ---------------------
    t
