It is present, only it has now been moved to pg_hba.conf. It is no
longer in postgresql.conf. My guess is that you tried it configured
the same way as in previous versions, where there was a global
parameter in postgresql.conf?

That page lists settings for pg_hba.conf, so I believe it is correct.
However, suggestions for improvements are always welcome :-)

In a very large part of the cases, the fully qualified hostname will
be the same as the fully qualified interface name for the only
interface that's configured.

Anyway, the whole reason for moving the krb_server_hostname parameter
into pg_hba.conf is to make it *more* flexible to configure situations
like this.
