you can use a simple sql to find it out.

try: select datname from pg_database ;

Thanks for the help!  That worked just fine.

I also found this (from within psql):

# \l
  List of databases
 Database  |  Owner
-----------+----------
 template0 | postgres
 template1 | postgres
 testdb    | postgres
(3 rows)

And this from command-line:

$ /usr/local/pgsql/bin/psql -l
Password:
  List of databases
 Database  |  Owner
-----------+----------
 template0 | postgres
 template1 | postgres
 testdb    | postgres
(3 rows)

Thanks again!
