ident authentication not working over loopback adapter

This is a bit backwards. ident authentication is working for me over
Unix domain sockets, but it isn't working over the loopback adapter.

Here is my /var/lib/pgsql/data/pg_hba.conf:

# Allow local and loopback users to connect to self-named databases
#
local sameuser ident sameuser
host sameuser 127.0.0.1 255.255.255.255 ident sameuser

# Allow password-based authentication for local users, loopback, and
# local subnet.
#
local all md5
host all 127.0.0.1 255.255.255.255 md5
host all 192.168.1.0 255.255.255.0 md5

I have installed the identd daemon, and 'nmap localhost' confirms that
it is listening on port 113.

Here is an example session. (I have created a PostgreSQL user named
'pilcher' and a database of the same name.)

[pilcher(at)home pilcher]$ psql
Welcome to psql, the PostgreSQL interactive terminal.

Type: \copyright for distribution terms
\h for help with SQL commands
\? for help on internal slash commands
\g or terminate with semicolon to execute query
\q to quit

pilcher=> \q
[pilcher(at)home pilcher]$ psql -h localhost
psql: FATAL 1: IDENT authentication failed for user "pilcher"

Anyone have any idea what's going on?

Notes: This is Red Hat Linux 8.0. Password authentication works over
Unix domain sockets or the loopback adapter.

Thanks!
