stored externally row_merge_buf_add(): Has strict assert that fixed length mismatch shouldn't happen while rebuilding the redundant row format table btr_index_rec_validate(): Fixed size column can be stored externally. So sum of inline stored length and external stored length of the column should be equal to total column length
