Well, like I said, it's not real pretty.  But the same is already true
of postgresql.conf.sample --- initdb edits that.  I don't see that
having it edit pg_hba.conf.sample too is so bad.

I don't think it would hurt them.  The editing will consist of a sed
script to comment or uncomment the line containg ::1, it wouldn't touch
anything else.

Bruce and I talked about that alternative too, but we felt that it made
more sense to keep the processing of pg_hba.conf.sample parallel to what
happens to postgresql.conf.sample.  Further down the road we might need
initdb-time checks to decide what to do to the sample file, just as we
already need for postgresql.conf.sample.
