Use an empty PostgreSQL database with the extension binaries available on its server. Set `DATABASE_URL`
to that database and follow any server setup requirements described above.

```bash
rent extension check --provider self-hosted
rent generate
rent migrate seal
rent migrate apply
cargo run
```

If your host preinstalls other extensions, declare those in RSL as well. For a database
with existing application tables, [baseline it first](/docs/using-rent/migrations#adopt-an-existing-database).

The included first migration installs `vector` before `pg_search`, which depends on it.
That reviewed migration also creates the `posts` table described by the schema.
