 Before enabling the extension you need to initialize `pgrx`. The easiest way to get started is to allow `pgrx` to manage its own version/s of Postgres:
 
 ```bash
-cargo pgrx init --pg16=download
+cargo pgrx init --pg17=download
 ```
 
 For more advanced configuration options, like building against an existing Postgres installation from e.g. Homebrew, see the [pgrx docs](https://github.com/pgcentralfoundation/pgrx)
 
 To start the database:
 
 ```bash
-cargo pgrx start pg16
+cargo pgrx start pg17
 ```
 
 To connect:
 
 ```bash
-cargo pgrx connect pg16
+cargo pgrx connect pg17
 ```
 
 Finally, to enable the `pg_graphql` extension in Postgres, execute the `create extension` statement. This extension creates its own schema/namespace named `graphql` to avoid naming conflicts.
