All constraints are named like that already, and NOT NULL constraints just inherited the same idea. The names are <table>_<column>_not_null for NOT NULL constraints. pg_dump goes great lengths to avoid printing constraint names when they have this pattern.
OK, this is helpful. Can \d do the same thing? I use a lot of NOT NULL constraints and I very seriously do not want \d (including \d+) to have an extra line for almost every column. It's just noise, and while my screen is large, it's still not infinite.
I do not want these constraint names cluttering the output either. That's why I propose moving them to a new \d++ command, where they will only bother you if you absolutely need them. But so far I have only one vote supporting that idea.
My suggestion is for \d+ to show NOT NULL constraints only if there is something weird going on (wrong name, duplicate constraints, …). If there is nothing weird about the constraint then explicitly listing it provides absolutely no information that is not given by "not null" in the "Nullable" column. Easier said than done I suppose. I'm just worried about my \d+ displays becoming less useful.
