Well, if you're only going to change this in HEAD, that might be an
acceptable limitation, but if you intend to back-patch I think not.
Older versions of createdb are probably significantly more likely to
be used with even-older servers.
Seems like it wouldn't be that hard to test the server version and only
reconnect if it's pre-8.2.
