I've had a quick look, and while I see the odd reference to PyPi in the archives, I'm not sure if there has ever been discussion of having a PyPi release for pgAdmin.
I am of course aware of the packaging changes w.r.t. psycopg2 and psycopg2-binary in 4.6, but did wonder if that might open the door in that regard?
This is of interest to me because when we deploy, we cannot avoid a dependency of PyPi for lots of stuff. But right now, in addition to that, we also manually maintain a dependency on a handful of packages such as pgAdmin. This in variably means we fall behind on these, and on balance, the minimal extra exposure to Pypi wuld be much preferable. I suspect that there are others in a similar position.
So, any thoughts on making pgAdmin4 available on PyPi??
Yes, but I just never got round to figuring out all the details. It's on my personal TODO list.
