Hi!
This is my first post to this list.
(Sorry for my bad english)
I decided to start small, but as it is in the TODO, then why not.
In TODO:
> Process pg_hba.conf keywords as case-insensitive
>http://archives.postgresql.org/pgsql-hackers/2009-09/msg00432.php
It seems to me reasonable to throw an error saying 'ALL' is not a valid
value and * not * reload the pg_hba.conf file.
It seems a good place parse_hba_line in src/backend/libpq/hba.c, and
use strcasecmp
for checks.
Patch attached, if is very simple,
