Re: psql: Add role's membership options to the \du+ command

Yes.  I dislike having the equivalent of null embedded within the output here.  I would rather label it for what it is.  As a membership without any attributes has no real purpose I don't see how the choice matters and at least empty both stands out visually and can be grepped.

The SQL language uses the words "by" and "from" in its syntax; I'm against avoiding them in our presentation here without a clearly superior alternative that doesn't require a majority of people to have to translate the symbol " / " back into the word " by " in order to read the output.

But if it is really a blocker then maybe we should produce 3 separate newline separated columns, one for the member of role, one for the list of attributes, and one with the grantor.  The column headers can be translated more easily as single nouns.  The readability quite probably would end up being equivalent (maybe even better) in tabular form instead of sentence form.
