Generally, if you are a member of a role, that means you are the role for
privilege-test purposes.  I'm not on board with adding "(or a member of
that role)" to every place it could conceivably be added; I think that
would be more annoying than helpful.

It might be worth clarifying this point in section 5.7,

https://www.postgresql.org/docs/devel/ddl-priv.html

but let's not duplicate that in every ref/ page.
