+**Important:** `cargo-pgrx` **must** be built using the same compiler as you'll use to build the rest of your project. Every time you update your Rust toolchain you have to also manually reinstall `cargo-pgrx`. See [Upgrading](#Upgrading), below.

+Once `cargo-pgrx` is ready you can initialize the "PGRX Home" directory:

 cargo pgrx init

-The `init` command downloads currently supported PostgreSQL versions, compiles them to `~/.pgrx/`, and runs `initdb`. It's also possible to use an existing (user-writable) PostgreSQL install, or install a subset of versions, see the [`README.md` of `cargo-pgrx` for details](cargo-pgrx/README.md#first-time-initialization).
