# Tests for WL#2818:
#   - Check that triggers created w/o DEFINER information work well:
#     - create the first trigger;
#     - manually remove definer information from corresponding TRG file;
#     - create the second trigger (the first trigger will be reloaded; check
#       that we receive a warning);
#     - check that the triggers loaded correctly;
