You can always re-create template1 from template0:
CREATE DATABASE template1 WITH TEMPLATE template0;

As far as I can tell, the only way to remove the template1 database is
to rename it. Maybe that's what happened. This query should tell you
the name of the database that used to be template1:
SELECT datname FROM pg_database WHERE datistemplate;
