Apparently a Debian-specific file, since I don't recognize it offhand
and none of the RedHat(-derived) boxen I run have it.

Aside from my grumpiness about all things Debian...

... this works Just Fine for me on a fairly-bare Sarge box, with
Postgres installed just to see what happens.

Since you seem to be missing a semi-critical file (Debian-specific,
unfortunately - and why it's in any way necessary is beyond me), try
creating /etc/postgresql/postgresql.env with this content:  (Watch for
linewraps)

======BEGIN
# postgresql debian package
#
# This section is supplied as part of the Debian package for PostgreSQL.
# It sets the environment for an ordinary user of PostgreSQL and should
# be executed by the .profile or equivalent for the postgres
administrator
#
# It is automatically read by all six frontend programs (in the
# postgresql-client package).

[ -r /etc/postgresql/postmaster.conf ] &&
        . /etc/postgresql/postmaster.conf

PGDATA=${POSTGRES_DATA:-/var/lib/postgres/data}
PGLIB=/usr/lib/postgresql/lib
PGACCESS_HOME=/usr/lib/postgresql/share/pgaccess
PGHOST=

export PGLIB PGDATA PGACCESS_HOME PGHOST
======END

If that doesn't help, try uninstalling the postgresql package, and
reinstalling it.  You may have to purge it and manually hunt down
leftover files before reinstalling.

Er, if this is truly PostgreSQL as installed from the standard Debian
package, I sincerely hope that you meant /etc/postgresql/pg_hba.conf.
FWIW, it looks identical to the fresh one I found just after installing.

I see 5 files in /etc/postgresql:

postgres@test2:/etc/postgresql$ ls -l
total 32
-rw-r-----  1 root postgres 4885 2005-05-18 04:33 pg_hba.conf
-rw-r-----  1 root postgres 1441 2005-05-18 04:33 pg_ident.conf
-rw-r--r--  1 root root     9058 2005-09-16 14:50 postgresql.conf
-rw-r--r--  1 root root      602 2005-05-18 04:33 postgresql.env
-rw-r--r--  1 root root     3458 2005-09-16 14:49 postmaster.conf

-kgd
(Debian just rubs me the wrong way.  I always end up fighting some
component instead of quickly and easily bending it to my usage.)
