SELinux is preventing /usr/bin/postgres from 'open' accesses on the directory postgres_data.

*****  Plugin file (36.8 confidence) suggests  *******************************

If you think this is caused by a badly mislabeled machine.
Then you need to fully relabel.
Do
touch /.autorelabel; reboot

If you want to allow postgres to have open access on the postgres_data directory
Then you need to change the label on postgres_data
Do
# semanage fcontext -a -t FILE_TYPE 'postgres_data'
where FILE_TYPE is one of the following: var_log_t, abrt_var_run_t, samba_var_t, avahi_var_run_t, net_conf_t, sysctl_crypto_t, setrans_var_run_t, sysctl_kernel_t, cron_spool_t, dirsrv_var_run_t, openct_var_run_t, nscd_var_run_t, nslcd_var_run_t, var_lib_t, sysctl_t, pcscd_var_run_t, abrt_t, slapd_var_run_t, bin_t, sssd_var_lib_t, lib_t, mnt_t, root_t, tmp_t, usr_t, var_t, device_t, system_dbusd_var_lib_t, etc_t, system_dbusd_var_run_t, postgresql_var_run_t, proc_t, var_lock_t, sysctl_t, bin_t, cert_t, selinux_config_t, textrel_shlib_t, tmp_t, usr_t, var_t, winbind_var_run_t, rpm_script_tmp_t, mail_spool_t, sssd_public_t, sysctl_type, autofs_t, device_t, devpts_t, security_t, locale_t, etc_t, postgresql_tmp_t, proc_t, sysfs_t, tmpfs_t, likewise_var_lib_t, default_t, hugetlbfs_t, rpm_tmp_t, var_run_t, krb5_conf_t, postgresql_db_t, postgresql_t, httpd_sys_content_t, postgresql_etc_t, postgresql_log_t, auth_cache_t, security_t, udev_tbl_t, var_spool_t, rpm_log_t, var_log_t, var_t, var_lib_t, var_run_t, dbusd_etc_t, logfile, proc_net_t, file_context_t, nscd_var_run_t, pcscd_var_run_t, selinux_config_t, tmp_t, var_t, var_t, default_context_t, etc_t, security_t, cgroup_t, root_t, var_run_t, var_run_t, sysfs_t, tmpfs_t. 
Then execute: 
restorecon -v 'postgres_data'

If you believe that postgres should be allowed open access on the postgres_data directory by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep postmaster /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
