You need to place a profile for the local postgres instance in `~/.dbt/profiles.yaml`. See below a sample config that should be a good starting point if you follow the instructions in the `database` dir of this project.
```yaml
dbtlearn:
outputs:
dev:
type: postgres
threads: 4
host: localhost
port: 5432
user: the user
pass: the password
dbname: airbnb
schema: dev
target: dev
```
Once you have set this up and the database as well, you can run `dbt debug` to ensure everything is set up correctly and dbt can reach the database.
