I finally got a chance to try out your suggestions, but it seems that something I'm doing is still wrong.
 
When I try the first method described below, I get this error:
 
You are now connected as new user postgres.
ERROR:  function plpgsql_call_handler already exists with same argument types
ERROR:  Language plpgsql already exists
\connect: FATAL 1:  IDENT authentication failed for user "cmortensen"
 
When I try the other method, I get this error:
 
pg_restore: [archiver (db)] could not execute query: ERROR:  function plpgsql_call_handler already exists with same argument types
 
I get the impression that the problem is deeper than just trying to backup, but being a very green novice to Postgres, I'm not sure where to start tracking the problem to its source...
 
Thanks for all your help so far :)

Hi Curtis,

> thanks for the advice.  i now have a different error. :(

I suspected you would, but without knowing the commands you were using
decided guessing would only be confusing!  Only the archive formats
from pg_dump are intended to be used with pg_restore.  The default
output can be restored by psql:

$ pg_dump fubar > fubar.sql
$ createdb fubar2
CREATE DATABASE
$ psql fubar2 < fubar.sql
You are now connected as new user giles.
CREATE
$

$ pg_dump --format=c fubar > fubar.dump
$ createdb fubar2
CREATE DATABASE
$ pg_restore --dbname=fubar2 < fubar.dump
pg_restore: [archiver] WARNING: Data restoration may fail because existing triggers cannot be disabled (no superuser user name specified).  This is only a problem when restoring into a database with already existing triggers.

Giles
