A large scale of these applications are not in the open, so the answer to that is probably a large yes for attndims. Funnily enough, I've worked on a game in PHP that uses Postgres as backend for some hobby project, and actually used this field now that I look at this code again. It was from a long time ago, and that's not in the open, but you get the idea.. -- Michael
