PostgreSQL Account and Object Timestamp Logging
Hello everyone,
I would like to ask if there are any built-in features or extensions in
open-source PostgreSQL—aside from the AUDIT mechanisms—that allow us to
query or log the creation time of user accounts and database objects.
The reason for this inquiry is that while audit logs do capture these
events, they may eventually be rotated out or removed due to housekeeping
policies. Having a dedicated table or view to permanently record the
creation or modification time of accounts and objects would be very helpful
for audit and security compliance purposes.
Thank you in advance for your insights!

That information is not captured/retained by a PostgreSQL cluster. See
many previous discussions from the mailing list archives.

Yes, indirectly, via event triggers:

But that's specific to a DB, does [NOT fire for CREATE USER/ROLE][1]https://www.postgresql.org/docs/current/event-trigger-matrix.html,
only some objects,
and unfortunately, must be SUPERUSER to install it, DB OWNER is not
enough (pity...).
