As per discussion on -hackers the attached patch creates the 'default'
database at initdb time as a default target for initial connections to
keep template1 free from connections and available as template source.
I consider this DB a system object, so it's created before
make_template0 sets the last_system_oid (wondering why template0 isn't
considered a system db too)
Regards,
Andreas
