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: conn.connection.connection.notices = list() conn.execute(stmt) if notices: print('----------') print('\n'.join(conn.connection.connection.notices)) print('----------') -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
