list,

I am trying pgBackRest on an RHEL 7.6 and old EDB 10 database cluster( a legacy application.)

I have installed pgbackrest through  package install on RHEL7.6

But unable to get the basic stanza-creation working It throws an error.

 /etc/pgbackrest.conf  as follows..

################################################

pg1-port = 5444

Postgres conf as follows...

listen_addresses = '*'        
port = 5444

unix_socket_directories = '/tmp'

archive_command = 'pgbackrest --stanza=demo archive-push %p'
archive_mode = on
log_filename = 'postgresql.log'
max_wal_senders = 3
wal_level = replica

ERROR  Getting as follows ..    What went wrong here ??

It complains about the password.  I followed the below tutorial link, but no mention of password (Where to supply password, what parameter where ?) setting here ==> https://pgbackrest.org/user-guide-rhel.html

This is about the user connecting to the db, in general, pgbackrest has to connect like any other app/user. So, change your .pgpass to contain smth like the below on the top of the file :

/tmp:5444:*:postgres:your_whatever_pgsql_password

and retry

Any hints welcome..  What am I missing here ??

Best,
