# title:        Operator REVOKE can modify rights granted to system tables at DB creation time
# decription:
#                    We create here NON-privileged user and revoke any right from him. Also create trivial table TEST.
#                    Then try to connect with as user and query non-system table TEST and system tables.
#                    Query to table TEST should be denied, but queries to RDB-tables should run OK and display their data.
