Currently on our RHEL 7.8 system, /etc/pgbackrest.conf is root:root and 633 perms.  Normally, that's ok, but is a horrible idea when it's a plaintext file, and stores the pgbackrest encryption password.

Would pgbackrest (or something else) break if I change it to postgres:postgres 600 perms?

Nothing will break as far as I know. As long as pgbackrest can read the file it will be happy.

Is there a better way of hiding the password so that only user postgres can see it?

You could use an environment variable in postgres' environment, see https://pgbackrest.org/command.html#introduction.

In this case it would be PGBACKREST_REPO1_CIPHER_PASS=xxx

Similarly there's PGBACKREST_REPO1_CIPHER_TYPE?
