Thank you so much. I changed devfrances to host in the pg_hba.conf file and
it worked. I thought "host" was a placeholder and I needed to put in an
actual machine name/ip. Thank you also for the link. I didn't see that the
first time around.

Sincerely,
Frances Collier

I am guessing that entering devfrances you are entering a dns hostname of
the machine to allow connections - this is what would replace the
192.168.1.23 address but dns hostnames are not supported in pg_hba.conf. You
can enter a network such as 192.168.1.0/24 to allow anyone in the local
network to connect.

You must enter host at the start of the line not the dns hostname of the
machine you want to allow a connection from.

If you read the top of the pg_hba.conf file you will find the first column
refers to the type of connection - accepted values are :-
local 
host 
hostssl 
hostnossl

A local connection is a client connection from the same machine as the
server. The host connections refer to clients connecting from another
machine over tcp.

So a line like
host    all all 192.168.1.23/32 password
Would allow a connection to any database using any login username from the
machine at 192.168.1.23 using password authentication.

You can use the hostssl and hostnossl to specify that the connection from
that machine must use an ssl connection or cannot connect with an ssl
connection.

http://www.postgresql.org/docs/8.1/interactive/client-authentication.html
Provides the full documentation on these settings.
