In [PR](apache#44166) we added migration for removing pickled data from `xcom` table. During my testing I noticed with `SQLite` [insert](https://github.com/apache/airflow/blob/main/airflow/migrations/versions/0049_3_0_0_remove_pickled_data_from_xcom_table.py#L88) statement is not working in case of upgrade. Changing condition to `hex(substr(value, 1, 1)) = '80'` works. Tested [here](apache#44533 (comment)). related: apache#44166
