Okay. But I couldn't find any such case for showing MVs in "tables" or
"table_privileges" view. In fact, I could see some more views under
information_schema that doesn't consider MVs, For e.g.
column_privileges.

Okay. However, I feel, if normal view can be treated as tables then
MVs could also be. Thanks,
