in state I have:

top.sls:
base:
  '*':
    - common
  'G@roles:postgresql-slave and G@environment:test':
    - match: compound
    - database.postgresql-slave


database/postgresql.sls:
postgresql:
  pkg.installed:
    - pkgs:
      - dev-db/postgresql
      - dev-db/postgis
      - dev-db/postgres-pg_modules

database/postgresql-slave.sls:
include postgresql

{% for conf_file in 'pg_hba.conf', 'pg_ident.conf', 'postgresql.conf', 'recovery.conf' %}
{{ conf_file }}:
  file.managed:
    - name: /etc/postgresql-9.5/{{ conf_file }}
    - source: salt://database/files/{{ conf_file }}
    - user: postgres

    - mode: 644
    - template: jinja
    - defaults:
        replication_password: {{ pillar['postgresql']['replication_password'] }}
{% endfor %}

salt shows this error:
