comment 'schema sync only' for alter table

"Alter table" as DDL will be replicated, but if replication fails, .frm files are not in sync with columnstore engine.

It is possible to repair it with resync again via mariabackup
or

drop table segment_playground_master restrict;

create table segment_playground_master "with all columns " comment 'schema sync only';

But the smartest way would be to adding comment 'schema sync only' for "alter table"
