Let me just point out that people who have already run initdb during
beta will not see this in their pg_hba.conf, nor in their
share/pg_hba.conf.sample, even after they have upgraded to a later beta,
unless they run initdb. However, we have bumped the catalog version for
something else so they should then get this change.

My point is if we change configuration files and then don't bump the
catalog version, the share/*.sample files get out of sync with the files
in /data, which can be kind of confusing.
