Hi,
I found some strange behaviour of postgres superuser password in my existing cluster, below is the basic outline of the setup.
1. version - postgres 12
2. replication - streaming replication async
3. OS- centos7
4. One Master, One Standby
I have identical pgpass files on both server postgres home directory.
So when I execute below command on slave node:
psql -h slave_hostname/ip -U postgres -d postgres -p 5432 -c "select pg_is_in_recovery"
I get error of password authentication:
psql: error: FATAL: password authentication failed for user "postgres"
password retrieved from file "/homedirectorypath/.pgpass"
But when I run the same command on master node:
psql -h slave_hostname/ip -U postgres -d postgres -p 5432 -c "select pg_is_in_recovery"
I don't get any errors and get the expected output as "t".
Note: the passwords in and path of both pgpass files are identical.
then why am I getting errors on the slave node for the same command even after having everything the same ?
Also, I tried the -W to enforce the password of postgres user but got the same issue on slave and no issue on master although the password is the same.
What am I missing here ? Please suggest.
Regards,
Atul
