Not working with postgresql 9.5

[joba12]

Works pretty fine with psql 9.4 on CentOS 7.2, but not with 9.5

Following error while running the playbook:

RUNNING HANDLER [patrik.uytterhoeven.PostgreSQL-For-RHEL6x : restart postgresql] ***
fatal: [localhost]: FAILED! => {"changed": false, "failed": true, "msg": "Job for postgresql-9.5.service failed because the control process exited with error code. See \"systemctl status postgresql-9.5.service\" and \"journalctl -xe\" for details.\n"}
        to retry, use: --limit @playbooks/database/main.retry

This is probably due to a parameter in the template that has been changed in 9.5
the template is not the best solution
what i want to do in the future is remove the template and make use of lineinfile this would make upgrading to a new version of postgres more easy but it will take a huge amount of time.
