Description (last modified by )
In ConnectionHandler, the explicit check for the DEFAULT_DB_ALIAS
key in the databases dict comes only after an attempt to lookup that key.
If you have at least one non-default db, but no default db, no dummy
default will be created for you, and the DEFAULT_DB_ALIAS key will
not be present. Under these circumstances, referencing the databases
property directly will give a KeyError instead of the intended
ImproperlyConfigured error.
Worse, if you try to access a non-default db, ensure_defaults will
catch that KeyError but misinterpret it as being for the non-default
db name (which does in fact exist in the dict).
