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(at)oz ~]$ psql -d template1
Welcome to psql 7.4.6, the PostgreSQL interactive terminal.

\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(at)oz ~]$ psql -d SCM
Welcome to psql 7.4.6, the PostgreSQL interactive terminal.

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).
