With GraalVM you can run any LLVM binary on JVM...

  That is true, graal's certainly more readily comparable.

JVM can run apps _compiled_ for it. WASM has the _exact same_ limitation. Someone put in the effort to get Postgres to compile for WASM. That's great :) Maybe someday every application will compile to WASM as the preferred choice over the linux interface. Compiling apps for different targets is VERY MUCH not a simple, low effort task though. Something like a database that must have an incredible number of optimizations in the way it makes syscalls, will have to a full stream of work to keep each target running well. It can be done. But if "one of these thigns is not like the other" with your three things- Docker is the odd duck out.
