`ALTER TABLE SET` command can also be used for changing the file location and
file format for
existing tables.
+If the table is cached, the `ALTER TABLE .. SET LOCATION` command clears
cached data of the table and all its dependents that refer to it. The cache
will be lazily filled when the next time the table or the dependents are
accessed.
Review comment:
- It is not applicable to all commands
