I tried psql_insert_copy method, but I got the following error message.
to_sql() got an unexpected keyword argument 'method'
Can anyone shed light on this?
method is a legitimate keyword:
https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.to_sql.html?highlight=to_sql#pandas.DataFrame.to_sql
So there must be something about how you used it.
Pandas version?
The actual code you used when the error occurred?

David
