Prefect Community

Hello. I was trying to run prefect locally with a local postgres install. I set up the config.toml
```[server.database]
connection_url = "<postgres://prefect:prefect@localhost:5432/postgres>"```
The problem that I am currently having now is that after putting in `prefect server start -ep` , Hasura is not able to connect properly and throws errors. Is there anyway I can rectify and solve this issue?

Are you just getting started with Prefect? Perhaps it would be easier for you to start directly with <https://discourse.prefect.io/t/should-i-start-with-prefect-2-0-orion-skipping-prefect-1-0/544|Prefect 2.0> then.

But if you want to use Prefect Server and Prefect 1.0 and use a local postgres database set up in Docker container, you can do:
```prefect server start --expose --use-volume # will by default use volume '~/.prefect/pg_data

# for more information, run:
prefect server start --help```
Or if you want to connect to an external DB (e.g. on AWS/GCP), you can attach external DB info this way:
```prefect server start --expose --external-postgres --postgres-url postgres://&lt;username&gt;:&lt;password&gt;@hostname:&lt;port&gt;/&lt;dbname&gt;```
