For what it's worth, I am quite happy with the current default of ident.

To make it work, you can install the `authd` package, then enable the `auth.socket` systemd service.  I've made it
listenonly on localhost, and disabled the encryption part of authd because I didn't want to figure out how to give
postgresthe appropriate key.
 

All-in-all, it makes for a seamless auth of local users/services to their own postgres databases running on localhost.
LastI checked, ident auth was only specified for the localhost addreses in pg_hba.conf.  (RHEL 8 has marked the "authd"
packageas deprecated without any explanation, though... it still works fine and is still present.)
