[ClusterLabs] Postgres never promoted

I got no further response regarding this topic.
If I am asking at the wrong place just let me know.
In any case I think the questions bellow could be answered here:
I it normal to have the crmd log line stating: "Pending pseudo op
ms_pgsql_promoted_0 on N/A (priority: 1000000, waiting: 11)"?
What does it mean?
Am I right thinking it means the cluster doesn't know where to promote the
MS resource? Or is it just normal because it appears only on the node that
should not be promoted?
Thank you
