Log Message:
-----------
Add description:

< This would require a new global table that is dumped to flat file for
< use by the postmaster. We do a similar thing for pg_shadow currently.
> This would add a function to load the SQL table from
> pg_hba.conf, and one to writes its contents to the flat file.
> The table should have a line number that is a float so rows
> can be inserted between existing rows, e.g. row 2.5 goes
> between row 2 and row 3.
