Hi All,
As part of the security standardization we are working on postgres super
user DB password rotation POC.
In that POC we have successfully rotated the password with the help of
password management tool.
We have noticed in patroni yml file for authentication we are explicitly
using super user name and credentials same for replicator user as well.
Is there any option we can pass this password instead of direct mentioning
or using .pgpass file.
Our intention here is we should not expose superuser password anywhere at
server level.
If we change the super user password at DB level should we update the same
in patroni yml every time ? If we not update that password in patroni yml
file is that impact anything of replication , API calls , primary and
replica connectivity?
And also pls share the best way to rotate the DB user password in postgres.
Your valuable suggestion is highly appreciated.
Regards,
SK.

I wrote a shell script to generate(*) a password, run the ALTER ROLE
command, push the VALID UNTIL out by 3 months, and either(**) "sed edit
.pgpass" or send the user an email with the new password.

Got the basics from a StackExchange post.

Thank you John,
Without .pgpass file patroni can connect to postgres ?
How patroni service works in this sinario?
Any insight on that postgres patroni configuration?
***//Authentication Config Sample from Patrnoi yml file // ***
=================
pgpass: /tmp/pgpass
authentication:
replication:
username: replicator
password: **********
superuser:
username: postgres
password: **********
===================
Regards,
SK

I don't use patroni, so just answered one specific question: how to rotate
a role password.

Well, I think you could also set the password via environment variables,
but I am not sure that is much better form a security point-of-view.
As an alternative, if you have unix sockets configured and keep the
superuser password empty, Patroni will use a local unix socket
connection, i.e. does not require a superuser password to be set.

If you want to use pg_rewind, you will need to configure an additional
pg_rewind user (with a password, cause pg_rewind connects remotely) if
your superuser has no password. If you add this to a running Patroni
cluster, I think Patroni will not GRANT the necessary function execution
rights to this pg_rewind user so you will have to do this yourself. This
should all be in the Patroni documentation.
