That adds extra unnecessary complexity. The code is written in C. There are C compilers for all CPUs. So just call the C code from <other language that's not JS>.

Well, a project has scope.

Looking at the repo, it started as postgres-in-the-browser. An abstract interface with C and wasm as targets is just more scope.

But it looks like the hard part of patching postgres to librar-ify it is already done agnostically in C.

So you just need to ctrl-f for "#if defined(__EMSCRIPTEN__)" to impl those else branches and port the emmake file to make.
