1. It fails silently if you have preferNativeBindings. It should show a warning to stdout.
2. In pnpm node_modules is not flattened so you need to explcitily declare the peer dep.
3. There should be the option to pass in the pg-native module. E.g. createPool(uri, {pgModule: require('pg-native')}).
4. Add a note to the readme.md about it.

Fix:

  "peerDependenciesMeta": {
    "pg-native": {
      "optional": true
    }
  },
