Hello, I am developing psycopg3 <https://www.psycopg.org/psycopg3/>, a major release of the psycopg2 PostgreSQL driver for Python. This release finally uses the advanced query protocol and server-side parameters binding, so adaptation of Python values to PostgreSQL data types has, at times, a different behaviour compared to the past. 100% compatibility is not a target: that's the whole point of creating a new package, but I am studying what is the sanest behaviour adaptation can have. I am exploring the best trade-offs in the choice of the mapping across types: I have a write-up at <https://www.varrazzo.com/blog/2020/11/07/psycopg3-adaptation/> and would like to get input from PostgreSQL people regards whether the choices we are making are the best possible ones. Looking forward to get your feedback, thank you very much! -- Daniele
