DataFrame.to_sql() is executing the following query:

SHOW FULL TABLES FROM `db`

When using pandas.DataFrame with sqlalchemy to insert into a MariaDB database. How do I prevent this from happening?
I haven't found any references to this in the docs or on SO:

Versions:
  Python:      3.7.4
  sqlalchemy:  1.3.4
  pandas:      1.0.3

To reproduce:

from pandas import DataFrame
import sqlalchemy as sql
import logging
logging.basicConfig()
logging.getLogger('sqlalchemy.engine').setLevel(logging.INFO)

conn = sql.create_engine('mysql://root@127.0.0.1:3306/db')
df = DataFrame([{
  'colA': 11,
  'colB': 'this is a thing',
}])
df.to_sql('TableA', conn, index=False)

Output:

...

INFO:sqlalchemy.engine.base.Engine:COMMIT
INFO:sqlalchemy.engine.base.Engine:BEGIN (implicit)
