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.
