Yeah, I do most of my work on my laptop these days, though my new machine's so much faster than it that it may draw me back ...
Anyway, I've upgrade acs-kernel to fix the problem you discovered with the user_tab_comment view. You can run acs-kernel/sql/postgresql/upgrade/upgrade-4.6.2-4.6.3.sql by hand, it just drops and redefines the view properly (we'll probably end up releasing a 4.6.3 quickly while we work on localization for 5.0)
