Hi Paul,

Thanks for your help. I have fixed that issue. Now I am getting one more issue. Can you help to fix the below error?

[postgres@post1 bin]$ /usr/pgsql-16/bin/repmgr -f /var/lib/pgsql/repmgr.conf cluster show

I'm not a repmgr guru but at first glance I would say that your config lacks two line breaks. It should probably look like this:

node_id=1
node_name=primary
conninfo='host=192.168.29.193 user=repmgr dbname=repmgr connect_timeout=2'
data_directory='/application/pgsql/data'
failover=automatic
promote_command='/usr/pgsql-16/bin/repmgr standby promote -f /var/lib/pgsql/repmgr.conf --log-to-file'
follow_command='/usr/pgsql-16/bin/repmgr standby follow -f /var/lib/pgsql/repmgr.conf --log-to-file --upstream-node-id=%n'
pg_bindir='/usr/pgsql-16/bin' log_file='/usr/pgsql-16/repmgr.log'

Cheers
Paul
