pgAdmin's icons have low quality and are not fully ready for hi-dpi
monitors. Icon for Linux app is only low res and has pure quality (see
attachment screenshot.png). Icon for Windows app is probably generated
from a jpeg and so it has some artefacts (see attachment zoomed.png).
I generated new app icons set (see attachment icons.zip):
Windows icon - it's clean and has 256px variant
OS X icon - it has added 1024px variant
Linux icons - new set with various sizes inc. scalable variant
