Yeah, this crossed my mind.  I thought that "superusers, roles with
privileges of the pg_read_all_stats_role, roles with privileges of the user
owning the session being reported on, and the user owning the session being
reported on" might be too long-winded and redundant.  But I see your point
that it might be a bit confusing.  Perhaps it could be trimmed down to
something like this:

    ... superusers, roles with privileges of the pg_read_all_stats role,
    and roles with privileges of the user owning the session being reported
    on (including the session owner).
