Do you still have template1?  If so, connect in single user mode, enter:
postgres template1
create database template0 with template template1
update pg_database set datallowconn = false where datname='template0';

Use CTRL-D to exit.

I think it'd be wise to issue a VACUUM FULL; VACUUM FREEZE in the newly
created template0 before disallowing connections to it.
