Docs say: Only the database owner or a superuser can rename a database;
non-superuser owners must also have the CREATEDB privilege.

Looks like a superuser must have CREATEDB too:

fduch@~=# SELECT usesuper, usecreatedb from pg_user where usename = 'fduch';
usesuper | usecreatedb
----------+-------------
t | f
(1 row)

fduch@~=# CREATE DATABASE test owner stat;
CREATE DATABASE
fduch@~=# ALTER DATABASE test RENAME TO work;
ERROR: permission denied to rename database
fduch@~=# ALTER DATABASE test OWNER TO fduch ;
ALTER DATABASE
fduch@~=# ALTER DATABASE test RENAME TO work;
ERROR: permission denied to rename database

At last:
fduch@~=# ALTER USER fduch CREATEDB ;
ALTER USER
fduch@~=# ALTER DATABASE test RENAME TO work;
ALTER DATABASE
fduch@~=# ALTER DATABASE work OWNER TO stat;
ALTER DATABASE
fduch@~=# ALTER DATABASE work RENAME TO test;
ALTER DATABASE

Yeah, the test in RenameDatabase is only looking at createdb and not at
superuserness. Seems like a bug to me --- or does anyone want to argue
that the code behavior is correct and the docs are wrong?

Tom has fixed this bug and backpatched it back to 7.4.X.
