## Postgres

Note that, if you're using docker-compose, the Postgres connector library [psycopg2](https://www.psycopg.org/docs/)
comes out of the box with Superset.

Postgres sample connection parameters:

- **User Name**: UserName
- **Password**: DBPassword
- **Database Host**:
  - For Localhost: localhost or 127.0.0.1
  - For On Prem: IP address or Host name
  - For AWS Endpoint
- **Database Name**: Database Name
- **Port**: default 5432

The connection string looks like:

```
postgresql://{username}:{password}@{host}:{port}/{database}
```

You can require SSL by adding `?sslmode=require` at the end:

```
postgresql://{username}:{password}@{host}:{port}/{database}?sslmode=require
```

You can read about the other SSL modes that Postgres supports in
[Table 31-1 from this documentation](https://www.postgresql.org/docs/9.1/libpq-ssl.html).

More information about PostgreSQL connection options can be found in the
[SQLAlchemy docs](https://docs.sqlalchemy.org/en/13/dialects/postgresql.html#module-sqlalchemy.dialects.postgresql.psycopg2)
and the
[PostgreSQL docs](https://www.postgresql.org/docs/9.1/libpq-connect.html#LIBPQ-PQCONNECTDBPARAMS).
