URL: https://github.com/apache/airflow/issues/65652#issuecomment-4347304784
I was able to reproduce this issue on my local environment.
## Environment
* Apache Airflow: 3.2.0
* Python: 3.12.3
* OS: Ubuntu (WSL2)
* Installation: local virtualenv
## Steps to reproduce
Run:
```bash
python -c 'import airflow.utils.db; print("IMPORTED airflow.utils.db")'
```
## Observed behavior
The following Alembic plugin setup logs are printed during import:
```text
setup plugin alembic.autogenerate.schemas
setup plugin alembic.autogenerate.tables
setup plugin alembic.autogenerate.types
setup plugin alembic.autogenerate.constraints
setup plugin alembic.autogenerate.defaults
setup plugin alembic.autogenerate.comments
IMPORTED airflow.utils.db
```
## Control test
Running:
```bash
python -c 'import airflow; print("IMPORTED airflow")'
```
Produces:
```text
IMPORTED airflow
```
(no Alembic logs)
## Additional confirmation
Running:
```bash
python -c 'import airflow.utils.db_manager; print("IMPORTED
airflow.utils.db_manager")'
```
produces the same Alembic plugin setup logs.
## Conclusion
The issue is reproducible.
The Alembic plugin initialization appears to be triggered during module
import (`airflow.utils.db` / `db_manager`), rather than being deferred to
migration-related operations.

Screenshots and logs demonstrating the reproduction are included.
