Yeah, I was wondering about that the other day. I agree that we probably don't need to worry anymore about reading 7.2 pg_dump output. However, people may be used to/depending on the current behavior in other ways. It's hard to be sure, but it is worth noting that it's been a long time since \connect arguments were only identifiers. We'd have to consider the impact on the connstring case, too. regards, tom lane
