When logging ROW_T_INSERT or ROW_T_UPDATE records, we did not normalize the DB_TRX_ID of the current transaction into 0 if the current transaction had started (modifying other tables) before the ALTER TABLE started. MDEV-13654 introduced this normalization for ROW_T_DELETE and for all operations with ADD PRIMARY KEY, in row_log_table_get_pk().
