We're still going to very large lengths to load pre-7.3 dumps; see
for instance ConvertTriggerToFK() in trigger.c. I'm not aware of any
policy that would suggest blowing off pre-8.1 dumps should be
acceptable. Yeah, it's true that the *recommended* procedure is to
use the newer pg_dump, but people aren't always in a position to do
that.
I think it might be sane to emit a WARNING suggesting that CREATEUSER
might not mean what you think, but failing is probably not good.
