Re: pgadmin4 3.5's dependency on psutil is a bit painful

Hi,

We need psutil to handle backend process management, ie allow the user to
terminate long-running backup or restore job. I don't see any alternative
to psutil at a moment which supports cross-platform process management like
psutil do.

I think the reason why there is no binary wheel is that it is hard to
maintain platform specific binary wheels.
