WARNING: Can't get <node-name> xlog location.

Hello,

I attempted to create an HA postgres cluster but the primary resource won't come to alive.
PostgreSQL version: 11.19
Pacemaker version: 2.1.4
OS Distribution: AlmaLinux 9.1

pacemaker.log is repeating below lines,

I'm sure that the xlog's location is correct when I created the resource.

Am I using the wrong packages?
Do you have any example commands to create this cluster?

The report names the PostgreSQL resource agent, Pacemaker logs, and the cluster and node-attribute status, but no source file or test. Start by reproducing the HA cluster setup with PostgreSQL 11.19 and Pacemaker 2.1.4, then trace the repeated xlog-location warnings and stopped resources. Done means the cause is identified and a verified fix or configuration resolution is recorded.
