I have configured streaming replication between one master and one standby server.
In the pg_hba.conf file of the master server, I have put the standby server's hostname instead of IP and due to which replication got broken and I started getting below error.
FATAL: no pg_hba.conf entry for replication connection from host "10.20.8.22", user "replication", SSL off
2023-11-30 12:00:25 PST|pid=24096|FATAL: XX000: could not connect to the primary server: FATAL: no pg_hba.conf entry for replication connection
from host "10.20.8.22", user "replication", SSL on
I put the ip of standby back in pg_hba.conf file of the master server and replication got started, though in the standby server I mentioned the hostname of master in primary_conninfo on the standby side.
So why is the master not reading the hostname of standby ? What am I missing here ?
You'd have to show us pg_hba.conf and /etc/hosts.
My guess, though, is that you're not taking the domain name into account.
