I can't help but feel that there should be something in the docs for 9.0 to specify this, since it is a behaviour difference from 8.4 and earlier. The docs (http://www.postgresql.org/docs/9.0/interactive/auth-pg-hba-conf.html) do say: "Recall that there is no real distinction between users and groups in PostgreSQL; a + mark really means "match any of the roles that are directly or indirectly members of this role", while a name without a + mark matches only that specific role" Maybe the docs should be embellished to also say "since a superuser is automatically considered a member of any group, it should be taken into account that names with a + mark will affect all superusers (although this was not the case prior to 9.0)" or something along those lines.
