postgres_database.present never works because call to postgres_user.present fails

Description of Issue/Question

When postgres_database.present tries to create a database and assign it to a user, it always fails with a python exception and a stack trace.

Setup

Using postures-formula from saltstack-formulas at revision 5cbf920fa7f7d277a5dd874f08157f15aad3a19e

Pillar Data:

postgres:
  #pg_hba.conf: salt://postgres/pg_hba.conf
  conf_dir: /etc/postgresql/9.4/main
  lookup:
    pkg: 'postgresql-9.4'
    pkg_client: 'postgresql-client-9.4'
    pkg_dev: 'postgresql-server-dev-9.4'
    pkg_contrib: 'postgresql-contrib-9.4'
    pg_hba: '/etc/postgresql/9.4/main/pg_hba.conf'
  version: 9.4

  users:
      provisioner_local:
        password: 'blabla'
        createdb: False

  acls:
    - ['host', 'provisioner_local', 'provisioner_local', '0.0.0.0/0', 'md5']


  databases:
    provisioner_local:
      owner: 'provisioner_local'
      user: 'provisioner_local'
      template: 'template0'
      lc_ctype: 'C.UTF-8'
      lc_collate: 'C.UTF-8'
   
  postgresconf: |
    listen_addresses = '0.0.0.0'

State:

local:
  - postgres

Steps to Reproduce Issue

Running salt-call state.apply will do everything correctly except creating the database (and setting the user as the owner). The user is created fine. This issue has been happening since Debian 8 and Salt 2016.3.x

Postgres says:

postgres=# \du
                                 List of roles
     Role name     |                   Attributes                   | Member of 
-------------------+------------------------------------------------+-----------
 postgres          | Superuser, Create role, Create DB, Replication | {}
 provisioner_local |                                                | {}

This is done in a fresh vagrant box, and fails every time.

Start with salt/states/postgres_database.py and follow the traceback into salt/modules/postgres.py and salt/modules/cmdmod.py. Reproduce the failure with salt-call state.apply using the supplied pillar data; done means the database is created with provisioner_local as owner without the CommandExecutionError.
