It depends how you use it. This used to happen all the time on non NT
versions of windows which had a low GDI handle space, like 32k or 64k.
Windows NT kernel has much more, I think around 1mb although I really
have no idea. GDI development kits tend to use extra handles because
they don't re-acquire handles for the DC, Brush, etc. Delphi is
notorious for this.
No doubt, you would have to have a lot of pgAdmin windows open for this
to happen, like 30 or more or some random number depending on what else
is open. Certain well known apps use a lot of handles like Microsoft
Visio. I only mentioned it because the behavior you get in this
scenario sounds like what was happening to this guy.
