You need to drop the `name: ` from your `notify`:

```
notify:
- restart postgres
```

Running Ansible 2.4.2.0 on OSX 10.13.2 (via macports), python version 3.6.4.

I'm running a playbook of some 100-odd tasks and this error occurs at some 
point in that operation.  I can repeatedly run the playbook and get 
successively closer to the end.

Some operations must run; if everything is skipped then no error occurs.  The 
stack trace usually seems to point to a handler, but I can't spot the error.

With "-vvv":

the full traceback was:

It would seem that the error is happening when notifications are collected, 
e.g. one task after which the failure occurs.  Note that this is one task in 
the middle of several which do the "notify":

- name: install hiredis 0.13 shared library
  become: yes
  copy: src={{ item.src }} dest={{ item.dest }} mode={{ item.mode }}
  with_items:
- { src: "libhiredis.so.0.13", dest: "/usr/lib64/", mode: '0755' }
  tags: provision, hiredis, redis_fdw
  notify:
- name: restart postgres

The handler definition:

---
- name: restart postgres
  become: yes
  service: name="{{ pg_service }}" state=restarted
- name: reload sysctl configuration
  become: yes
  shell: sysctl -p /etc/sysctl.conf
