Error: Cannot find module 'pg'

[SantiagoRR2004]

I am creating this issue because I believe that pg should be a dependencies and not an optionalDependencies in package.json. In some computers executing node pokemon-showdown returns an error because pg isn't being installed.

The Node version is v24.13.0. Can I make a pull request changing that file?

The root of this issue is that lib/database.ts always imports mysql and pg, despite the fact that both features are OFF by default.

Fix is simple enough, just move back to require, and have both functions become placeholders if the dependency is not installed.
