In pg_hba.conf is a link to this file. As some users don't have filesystem privileges, but are allowed to add users, they have to be able to call a function in postgres which adds that user to the file.

In 8.2, you might have another option. There is now a CONNECT privilege for
databases. So you don't need to list all of your users individually in
the pg_hba.conf file to give only some of them access to particular
databases.
