Apologies, I left out a key piece of information:
The role dumpable has superuser privileges, and this is the reason that
dumpable is able to dump the database. As noted in the docs, superuser,
createdb, and createrole privs don't seem to inherit. If I remove
superuser from role dumpable, that role can't do pg_dump either.

As a point of explanation, this is part of a migration to get individual
users away from requiring superuser privs. Eventually, I plan to have
ACLs on all database objects such that I can remove superuser from the
dumpable role, but if I could get other roles to inherit the superuser
priv, it would make migration a lot easier.
