postgresql - How to promote slave to master postgres in pacemaker

Question

I setup pacemaker postgresql synchronization.

And for testing I reboot the master(server1). so now one of my client(server2) become master.

pcs status
Cluster name: vipcluster
Stack: corosync
Current DC: server1 (version 1.1.16-94ff4df) - partition with quorum
Last updated: Tue Jan  5 13:28:46 2021
Last change: Tue Jan  5 11:53:03 2021 by root via cibadmin on server1

3 nodes configured
8 resources configured

Online: [ server1 server2 server3 ]

Full list of resources:

 MasterVip      (ocf::heartbeat:IPaddr2):       Started server2
 Apache (ocf::heartbeat:apache):        Started server2
 Master/Slave Set: TestDataClone [Test]
     Masters: [ server1 ]
     Slaves: [ server2 ]
 TestFS (ocf::heartbeat:Filesystem):    Started server1
 Master/Slave Set: pgsql-ha [pgsqld]
     Masters: [ server2 ]
     Slaves: [ server1 server3 ]

Daemon Status:
  corosync: active/enabled
  pacemaker: active/enabled
  pcsd: active/enabled

Now I need to maker server1 to be master. How can I do that? I thought it will do automatically

And I notice on postgresql status some changes , missing one server.

su - postgres
postgres@oreo:~$ psql -c "select application_name, state, sync_priority, sync_state from pg_stat_replication;"
 application_name |   state   | sync_priority | sync_state
------------------+-----------+---------------+------------
 server3          | streaming |             0 | async
(1 row)
