I don't quite get what you mean by upgrading to scram-sha256. I installed postgres 13. I haven't upgraded anything yet.

Did you correctly upgrade your whole environment to scram-sha-256?

To upgrade an existing installation from md5 to scram-sha-256, after having ensured that all client libraries in use are new enough to support SCRAM, set password_encryption = 'scram-sha-256' in postgresql.conf, make all users set new passwords, and change the authentication method specifications in pg_hba.conf to scram-sha-256.

The log says:

> FATAL:  password authentication failed for user "centos"
> DETAIL:  Connection matched pg_hba.conf line 88: "host    user       password          0.0.0.0/0               scram-sha-256"

 

I can't understand where is the problem as both psql and pgadmin connect without problems using the same password

Sorry. This was the replication section:

local   replication     all                                     peer
host    replication     all             127.0.0.1/32            scram-sha-256
host    replication     all             ::1/128                 scram-sha-256

I don't believe that.

This is how it looks by default:

# Allow replication connections from localhost, by a user with the
# replication privilege.
local   replication     all                                     trust
host    replication     all             127.0.0.1/32            trust
host    replication     all             ::1/128                 trust
