Yes, good point. In thinking about this, I think we are better having
the load() function load the file into a temporary table, which can then
be modified and flushed down to the flat file. Another option is that
queries to the table automatically read the flat file, but that might
force writes to the file on first update, so that might be bad.

It allows remote administration, and by using columns for the
pg_hba.conf lines (except for comments), we are making it somewhat
easier.
