How to ALTER EXTENSION name OWNER TO new_owner ?

Hi,

Why does
ALTER EXTENSION name OWNER TO new_owner;
not exist?

I have a bunch of extensions that were installed by a role that I want
to drop. So I thought I would do like I do for other object types:
ALTER <object_type> name OWNER TO new_owner;

But that doesn't exist for extensions. I also can't drop the extension
and recreate it because other objects depend on it.

What can I do?

This is on PostgreSQL 9.3.

Thanks,

Colin
