> Modify:
>  - unique -> non unique, non-unique -> unique, or no change
>  - nullable -> not-nullable, not-nullable -> nullable, or no
>    change
>  - a wider type is altered to a more narrow type, or vice versa,
>    or the type types are incompatible, or no change,
>  - key part added, removed, or all key parts changed, or no key
>    parts changed.

A few more dimensions: 

 - engine=memtx or engine=vinyl.
 - a space format is defined or not
 - a space is empty or not
 - the alter happens during run time, replica join, or WAL recovery
