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! -- Daniele
