That's great. It doesn't seem to be too active, though - only three issues were updated in 2014, and none so far in 2015. I bet that's because it's hard to find: the bug tracker is not mentioned on the pgAdmin Development page at
It's more an internal bugtracker than something else. I used to use it quite frequently when I was working on pgAdmin's code, but I'm pretty sure I was the only one.
In any case, it's quite obsolete, unused, and would better be dropped rather than publicized.
