In this case, a dba would drop anything not neccessary, including
INFORMATION_SCHEMA. We also could provide an initdb switch to omit that
pg_system db (and more non-vital stuff).
I particularly dislike the name "default" for that database, because
we'd have to expect users to place their user data there regularly (as
in the public schema), which is just what should *not* happen. So the
pg_ prefix should be used, the docs say clearly enough "don't touch pg_%
objects unless you know exactly what you do".
