TODO:

• Migration action sorting procedure need some fixes. When many foreign keys in tables, there is a bug with action order. Now, please check it manually (--preview option)
• Need to check (and maybe fix) field types: BLOB, RANGE, ARRAY, GEOMETRY, GEOGRAPHY
• Downgrade is not supported, add it
• This module tested with postgresql (I use it with my projects). Test with mysql and sqlite.
