Review Comment:
   The error message obtained by executing this SQL is:
   
   ```
   A column, variable, or function parameter with name `point` cannot be 
resolved. Did you mean one of the following in table 
`testcat`.`ns1`.`ns2`.`table_name`? [`id`]
   ```
   
    This seems a bit strange, is it suggesting that users should change to 
execute 
   
   ```
   ALTER TABLE $t ADD COLUMN id.z double
   ```
