Hello,

a customer recently mentioned that they'd like to be able to see when a
(md5, scram) role had their password last changed. 

Use-cases for this would be issueing an initial password and then later
making sure it got changed, or auditing that all passwords get changed
once a year. You can do that via external authentication methods like
ldap/gss-api/pam but in some setups those might not be available to the
DBAs.

I guess it would amount to adding a column like rolpasswordchanged to
pg_authid and updating it when rolpassword changes, but maybe there is a
better way?

The same was requested in https://dba.stackexchange.com/questions/91252/
how-to-know-when-postgresql-password-is-changed so I was wondering
whether this would be a welcome change/addition, or whether people think
it's not worth bothering to implement it?

Thoughts?



Michael
