I figured out the keyword is NOTICES.
However this section of the docs doesn't work / didn't had any effect:
https://docs.sqlalchemy.org/en/13/dialects/postgresql.html#notice-logging
What worked was to manually clear and print
conn.connection.connection.notices like this:
if notices:

normally be displayed in psql's command line.
How can I do so with SQLAlchemy + psychopg2?
