You need to quote the identifier using double-quotes to avoid
case-folding (this is a general rule):

ALTER DATABASE "MixedCase" RENAME TO anything_else;

Yes, it's actually a variation on the SQL standard, which specifies
forcing to upper case (as Oracle does).

The admin tool is a separate project and works by its own rules.

The FAQ has a good section on identifier case-folding and quoting, I
think.  Probably worth a read.
