Postgres and alembic - Assuming SERIAL sequence

I have a postgres DB, which I manage through SQLAlchemy and alembic (for migrations). When creating a DB migration through alembic, I get the following INFO in the console.

INFO  [alembic.ddl.postgresql] Detected sequence named 'my_table_name_id_seq' as owned by integer column 'my_table_name(id)', assuming SERIAL and omitting

My model looks like

class CopyJob(db.Model):
    __tablename__ = "my_table_name"

    id = db.Column(db.Integer, primary_key=True, autoincrement=True)

I interpret the above as a warning. One line is generated for each of my tables. I have two questions:

  • Am I doing something wrong when getting the warning above
  • What should I fix / explicitly set, in order to make it go away. Migrations are too verbose.

Thank you!

After digging a bit into alembic code it doesn't look like a warning. Alembic just informs that the sequence it checks turns out to be a SERIAL. Therefore, there's no point in trying to somehow fix the issue. If the message bothers you, you can increase the log level to WARNING as was suggested in the comments, otherwise, there seems to be no workaround.
