## Requirements
|
|
|
|
### Database User
|
|
|
|
This source only uses standard authentication. You will need to [create a
|
|
PostgreSQL user][pg-users] to login to the database with.
|
|
|
|
[pg-users]: https://www.postgresql.org/docs/current/sql-createuser.html
|
|
|
|
## Example
|
|
|
|
```yaml
|
|
sources:
|
|
my-pg-source:
|
|
kind: postgres
|
|
host: 127.0.0.1
|
|
port: 5432
|
|
database: my_db
|
|
user: ${USER_NAME}
|
|
password: ${PASSWORD}
|
|
```
|
|
|
|
{{< notice tip >}}
|
|
Use environment variable replacement with the format ${ENV_NAME}
|
|
instead of hardcoding your secrets into the configuration file.
