Since the pg_hba.conf file is located in the /etc path, the pg_read_file
command fails with an error of
"could not open file "pg_hba.conf" for reading: No such file or direcotry"
It also won't allow use of the absolute path.
The answer I found was to use the following command:
postgres=# \! exec cat /etc/postgresql/8.3/main/pg_hba.conf
