> SQLAlchemy has an eDSL of SQL, so you can skip the whole ORM/table mapping layer, and just use it to programmatically construct SQL syntax

Yes, this is called SQLAlchemy Core: http://docs.sqlalchemy.org/en/latest/core/

You can also just use psycopg (the Postgres driver layer) directly, it’s surprisingly ergonomic in my (limited) experience.
