I have meet the similar issue when the postgres is not stopped normally. 
 
You could run pg_controldata to check if your postgres status is shutdown/shutdown in recovery.

I change the /usr/lib/ocf/resource.d/heartbeat/pgsqlms to avoid this problem:

elsif ( $pgisready_rc == 2 ) {
# The instance is not listening.
# We check the process status using pg_ctl status and check
# if it was propertly shut down using pg_controldata.
ocf_log( 'debug', 'pgsql_monitor: instance "%s" is not listening',
$OCF_RESOURCE_INSTANCE );
# return _confirm_stopped();       # remove this line
return $OCF_NOT_RUNNING; 
}

Hello Andrew,

Could you enable debug logs in Pacemaker?

With Centos you have to edit PCMK_debug variable in /etc/sysconfig/pacemaker :

PCMK_debug=crmd,pengine,lrmd

This should give you more information in logs. Monitor action in PAF should report why the cluster doesn't start :
