    Description

      I couldn't find it in the current tests, so don't know if it's intentional.

      create or replace table t1 (i int, s bigint unsigned as row start, e bigint unsigned as row end, period for system_time(s,e)) with system versioning;
      		 
      insert into t1 (i) values (1),(2);
      		 
      update t1 set i = 3;


      MariaDB [test]> select * from t1 for system_time all;
