pgAdmin auto-starting

Hi all,

Not a problem as such, more a surprise - every time I start my laptop 
and log in, a pgAdmin window starts up too. Is this expected behaviour?

I'm using pgAdmin 4 version 3.5, running on Debian Stretch with KDE 
Plasma, installed via apt from apt.postgresql.org; pgAdmin is running in 
desktop mode.

I know that the pgAdmin server has to start in the background, and 
indeed it does because I can see the icon in the system tray; and 
everything is working fine. But is it normal for it to open a window on 
first login to the computer? There's no entry for it where the KDE docs 
say to expect:

   ~/.config/autostart
   ~/.config/plasma-workspace/env

Thanks,

Ray.
