If you don't say "-t template0" then what you get is a database cloned
from template1 instead of template0. It sounds to me like you have
(either intentionally or accidentally) added some objects to template1,
and your code is relying on those objects being there in a newly-created
database. See
http://www.postgresql.org/docs/9.0/static/manage-ag-templatedbs.html
Whether having extra stuff in template1 is a good thing or not is
something that depends on your individual situation ... but a lot of
people have found it to be a foot-gun.
