hi, i tried the exact setup that you described here, but unfortunately i had to restart the new master(former slave)  in order to get the new settings and this will conduct to a downtime and service interruption.
anyway thanks for sharing your experience.

 so, just to make sure that i understand: 
after the master failed, the slave become the new master, the you have changed postgresql.conf from master to slave and viceversa and restarted the old master as slave ?

	hi

we did a new shell script named recovery_config_chage.sh at standby server.
the script I wanted to change the fail down postgres master config ,let it start as standby server
and build the communication with the former standby now is master server,then started it by remotestart.sh 

the above hopes to help you something
