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?
Interesting - I wasn't aware there was a faster method than "COPY ... FROM ... CSV"
Maybe my best input is that I've always found COPY/FROM/CSV to be insanely fast and really easy to write from any standard console or ORM, so maybe the fractional performance increase from other methods isn't worth it, given how performant, reliable and easy to use this approach is? Not really an answer but food for thought..
