https://github.com/vapor/postgres-nio implements the protocol (in a Kotlin like language :).

• no native c/kotlin code, use Kotlin with Ktor
• No local libpq installation, no path problems
• Smaller binary size?
• should work on Windows too
• Jvm target too
• What about WASI?

Alternative: Convert R2DBC Postgresql to Kotlin and use kotlinx coroutines
