I agree with Michael, I would leave the postgres DB in place.  I currently
run 8.0.1 which does not create the postgres DB automatically and make a
point to create it to use as my "maintenance" DB for such things as pgAdmin
connections etc.  I was unaware that newer releases auto-create this DB,
good move!  I only wish I could upgrade to at least 8.1 to take advantage of
all the new features and fixes.

Here's an excerpt from the 8.1 Release Notes:

* Make initdb create a new standard database called postgres, and
  convert utilities to use postgres rather than template1 for
  standard lookups (Dave)

  In prior releases, template1 was used both as a default connection
  for utilities like createuser, and as a template for new databases.
  This caused CREATE DATABASE to sometimes fail, because a new
  database cannot be created if anyone else is in the template
  database. With this change, the default connection database is
  now postgres, meaning it is much less likely someone will be using
  template1 during CREATE DATABASE.

Some utilities expect to find the "postgres" database and they'll
fail if they can't connect to it.  I'd recommend leaving it in
place.
