#   2. check that if DEFINER-clause specifies non-current user, SUPER privilege

#   3. check that if DEFINER-clause specifies non-existent user, a warning is
#     emitted.
#   4. check that SHOW CREATE PROCEDURE | FUNCTION works correctly;

# The following cases are tested in other test suites:
#   - check that mysqldump dumps new attribute correctly;
#   - check that slave replicates CREATE-statements with explicitly specified
#     DEFINER correctly.
