Types adaptation in psycopg3

[Daniele Varrazzo <daniele.varrazzo@xxxxxxxxx>]

Hello,

I wrote a description of the psycopg3 adaptation system and the main
differences compared to psycopg2: available at
https://www.psycopg.org/articles/2020/11/24/psycopg3-adaptation/

Initial API docs are available at
https://www.psycopg.org/psycopg3/docs/adaptation.html

Feedback is welcome. Cheers!
