and various async context managers. Which version of Prefect are you using? That will really help me in diving into this further.seto

correctly to point to Postgres.
2. Starting the Server: After setting the URL, use prefect server start
.
3. Running Migrations: Prefect uses Alembic for migrations. Run:
- prefect server database upgrade -y
to upgrade
- prefect server database downgrade -y
to downgrade
For a comprehensive guide, refer to the self-hosting guide.
4. Generating Migration Files: If you need to generate new migrations, use:
- prefect server database revision --autogenerate -m "<migration name>"
Again, for more details, refer to Prefect's developer contribution guide.
For more specific instances and code, you might want to dig through this GitHub issue.
Now, go ahead and enjoy your day of config fiddling.
