Mostly for my curiosity: What would be their use case?
Thank you for showing interest in that patch.
For my customer, their use case is to be able from an SQL client to double check they're on the right host before doing things that could become a production disaster.
I see also another use case: being able to identify postgres metrics on a monitoring tool. Look at the hack pg_staviz uses here:
I only see limited usability, considering that the local user's hostname can be very different from the hostname used in the url that connects to that PostgreSQL instance.
Agreed, depending on how hosts and dns are set, it can be useless. But normally, companies have host making standards to avoid that.
