Re: [pgAdmin4][Patch] To fix the issue in Debugger module

Hi

I'm unable to properly test this, as the debugger doesn't even seem to
launch for a non-superuser. I just get a white tab, and a whole lot of
polling indefinitely. Can you debug if you're not a superuser, but you
own the function?

Looking at the patch itself, I wonder if the logic is still a little
off. You need to be a superuser to use indirect debugging (because of
the DOS potential), so shouldn't the superuser check be changed to "if
!superuser then throw error"? As it is, if you're not superuser then
it just skips the check for the plugin, which seems like it'll never
end well.
