Change native export method

[avaly]

Starting with node.js v14.13.0 CommonJS modules are parsed to detect their exports bindings. In this case pg is triggering the lazy loading of the pg-native dependency.

Please consider exporting the native feature in another compatible way.

See: nodejs/node#35859

The error message will be fixed by brianc/node-postgres#2372. I don’t think skipping loading the module tree entirely will happen in 8.x; it’s hard to make backwards-compatible, for not much benefit.
