Yes you can, in 8.3 anyway:
postgres=# create database "TeSt";
CREATE DATABASE
postgres=# \l
List of databases
Name | Owner | Encoding
------------------+----------+----------
[snip]
teSt | postgres | UTF8
[snip]
postgres=# alter database "TeSt" rename to "tEsT";
ALTER DATABASE
postgres=# \l
List of databases
Name | Owner | Encoding
------------------+----------+----------
[snip]
tEsT | postgres | UTF8

Have you tried quoting the database name, thus? -
ALTER DATABASE "MixedCase" RENAME TO anything_else;
This ought to do it.

No, it's PostgreSQL's (well-documented) behaviour - as you noted, it
folds names to lower-case unless you specifically quote them. I'd hazard
a guess that PgAdmin is quoting the database name behind the scenes,
hence you can create mixed-case names.
