permission item:

< 	o %Allow pg_hba.conf settings to be controlled via SQL
> 	o %Allow per-database permissions to be set via GRANT
< 	  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.
> 	  Allow database connection checks based on GRANT rules in
> 	  addition to the existing access checks in pg_hba.conf.
