Hello,
I have written an article describing the new COPY support available in
psycopg3: it is a big improvement to what is available in psycopg2,
allowing COPY from a stream of Python objects, async operations,
binary copy. You can find it at
https://www.psycopg.org/articles/2020/11/15/psycopg3-copy/
In the next few days I would like to write more about the new main
features of psycopg3 and differences with psycopg2. In the meantime I
am writing down a first draft of the documentation
(https://www.psycopg.org/psycopg3/docs/)... and of course the code
that remains to write.
More information about the psycopg3 project is at
https://www.psycopg.org/psycopg3/ Thank you very much!
