RE: Streaming Replication

Double check all the info is correct on the primary_conninfo line:

primary_conninfo = 'host=primary host port=5432 user=replication password=replication'

And check your logs.  It probably says something like cannot connect to host primary.

Hello Team,

I am setting a streaming replication by using two different host there is no output of select * from pg_stat_replication; I have set the parameters on both side.

Host names are :

(10.29.15.244)
(10.29.15.25)

postgres=# select * from pg_stat_replication;

pid | usesysid | usename | application_name | client_addr | client_hostname | client_port | backend_start | backend_xmin | state | sent_lsn | write_lsn | flush_lsn | replay_lsn | write_lag | flush_lag | replay_lag | sync_priority | sync_state
