Hi all,

This is the continuation to the discussion that we had in the hacker's 
list.
http://archives.postgresql.org/pgsql-hackers/2007-08/msg00684.php


Here, I like to add some details in 20.2.6. PAM authentication section.
http://www.postgresql.org/docs/8.2/interactive/auth-methods.html#AUTH-PAM

Can someone review and make changes, if required? Thanks.

+      The local UNIX user authentication is not permitted,
+      because the postgres server is started by a non-root user.
+      In order to enable this functionality, the root user must provide
+      additional permissions to the postgres user (for reading 
/etc/shadow file).
