Using drop database from psql

When I try to drop a database, whether I have opened it or some other
database, I get told it doesn't exist. The message changes the case of
the database name, but that may be a feature of SQL.

They system is a Fedore Core 3 server running
postgresql-server-7.4.6-1.FC3.1.

Here is the output:

[postgres@oz ~]$ psql -d template1
Welcome to psql 7.4.6, 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

template1=# \l
        List of databases
   Name    |  Owner   | Encoding
-----------+----------+-----------
 SCM       | postgres | SQL_ASCII
 SCMTST    | lbarnes  | SQL_ASCII
 template0 | postgres | SQL_ASCII
 template1 | postgres | SQL_ASCII
(4 rows)

template1=# \q
[postgres@oz ~]$ psql -d SCM
Welcome to psql 7.4.6, the PostgreSQL interactive terminal.

       \g or terminate with semicolon to execute query
       \q to quit

SCM=# drop database SCM;
ERROR:  database "scm" does not exist



Can anyone cast light on this? The database is empty, and I want to
recreate it with a different owner (which may be a task more easily done
with some other method).
