I agree with the sentiment, but it might help to distinguish between surprising behavior vs. surprising grammar.
In existing postgresql releases, having CREATEROLE means you can give away most attributes, including ones you yourself don't have (createdb, login). So we already have the concept of NOFOO WITH ADMIN OPTION, we just don't call it that. In pre-v8 patches on this thread, I got rid of that; you *must* have the attribute to give it away. But maybe that was too restrictive, and we need a way to specify, attribute by attribute, how this works. Is this just a problem of surprising grammar? Is it surprising behavior? If the latter, I'm inclined to give up this WIP as having been a bad move. If the former, I'll try to propose some less objectionable grammar.
