It seems the problem is with the psycopg2 library.
It may not be installed properly.

Please run python in interactive mode.
And, import psycopg2.

Right, forced an upgrade via pip2 and it overwrote the existing psycopg2. In interactive mode psycopg2 now imports correctly.
Now, when I run step 3 from web directory the command is accepted but there is no output. The command appears to hang - ctrl C will interrupt it cleanly, I can see from Gnome monitor that a python instance has started but all cores are quiet at minimum usage. Not sure what I should expect to see at this point. Runtime pgAdmin4 still not working.
