ALTER TABLE CHANGE COLUMN c1 c1 bigint NOT NULL - generates error if table uses SYSTEM VERSIONING

Details

    Description

      If you issue an ALTER TABLE to make a column that is a foreign key NOT NULL you get the following error:

      Cannot change column 'c1': used in a foreign key constraint 'p2c_ibfk_1'

      In prior versions of MariaDB this was allowed and did not generate an error. Further, if you issue an ALTER TABLE to make a column that is a foreign key NULLable you do NOT get any error message.
