# Check the layout of information_schema.user_privileges, permissions and
# the impact of CREATE/ALTER/DROP SCHEMA on it.
#
# Note:
#    This test is not intended
#    - to show information about the all time existing tables
#      within the databases information_schema and mysql
#    - for checking storage engine properties
#      Therefore please do not alter $engine_type and $other_engine_type.
