Hi,
I have postgres 12 running in centos7.
I recently have configured streaming replication from master to standby using below command:
/usr/bin/pg_basebackup -h <master ip> -p 5432 -U replication -D /path/of/data/directory/ -Fp -R -Xs -P -c fast
It was successfully configured but when I query pg_stat_replication I don't get the hostname in output:
postgres=# select * from pg_stat_Replication;
-[ RECORD 1 ]----+------------------------------

usesysid | 16384

So please help me understand the reason for this and how I will fix this issue of having a respective hostname in this catalog.

Atul
