Lightman 313e14d220 [Bugfix] (ROLLUP) fix the coredump when add rollup by link schema change (#15654)
Because of the rollup has the same keys and the keys's order is same, BE will do linked schema change. The base tablet's segments will link to the new rollup tablet. But the unique id from the base tablet is starting from 0 and as the rollup tablet also. In this case, the unique id 4 in the base table is column 'city', but in the rollup tablet is 'cost'. It will decode the varcode page to bigint page so that be coredump. It needs to be rejected.

I think that if a rollup add by link schema change, it means this rollup is redundant. It brings no additional revenue and wastes storage space. So It needs to be rejected.
