That's all very good but in doing so they disabled the ability to edit
the files through pg_file_read and pg_file_write, so this patch needs
more thought or handling on their part. It works fine in pristine
PostgreSQL, so it's not our bug. I assume pgAdmin is unable to edit the
config files in Debian due to this problem.
For example, perhaps there could be a new pair of functions
pg_read_hba_file/pg_write_hba_file that would work even if the files are
placed in other directories, but they (Debian) would need to propose it.
