The pgloader tool will import your data as batches of N lines, you get
to say how many lines you want to consider in each transaction. Plus,
you can have more than one python thread importing your big file, either
sharing one writer and having the other threads doing the parsing and
COPY, or having N independent threads doing the reading/parsing/COPY.

Hope this helps,
