It's possible it got created as a side effect of the system upgrade.

Are there any connections to it on the server? You can check with ps.

Deleting template0 or template1 (unless you're just going to recreate it
from template0) is a bad idea. They're the template databases from which
new databases are created (IIRC, template0 is just system things and
template1 can include anything you want to be clone in newly created
databases - such as language handlers, or wahtever).
