I know that since the launch of pgAdmin 4 in 2016, pgAdmin has been using a web-based model, as announced as early as 2014. You only need to do a little research on the Web to understand all the reasons behind this choice, which I do not seek to question.
However, I wonder if it would be relevant to keep pgAdmin 3 alive. I'm not so much talking about improving the interface of pgAdmin 3, but simply about keeping the software functional in new systems. I tried to install it in the latest versions of Linux Mint and Ubuntu, but the software keeps bugging, which it didn't do in older versions of the same systems 5 or 6 years ago.
Do you think there's a possibility that people could fix pgAdmin 3, even if it means making a fork or whatever? Because, although pgAdmin 4 and other tools such as OmniDB and DBeaver are probably excellent, some people, for various reasons, might want to continue using pgAdmin 3 in 2021. I'm not an expert in the field, but I'm thinking that maybe someone here might be able to save this nice little application software from disappearing by investing a few days to maintain it.
FWIW there is a fork here which is making some attempt to keep it up-to-date with recent PostgreSQL versions:
