Failed to build on Windows (missing pg_config)

I'm trying to build a new stack haskell app on Windows 10 and I get this error message:

Is there a way to skip the pg_config requirement? As I don't intend to install postgresql locally on this machine

you don't need to install psql, just the psql developer libraries. on arch and alpine these are called postgresql-libs. There's surely an analogue for windows
