Ok. So an extension using more than one schema is out, right? Not that I
can see a strong use case, just thinking out loud.
Also, do we keep the current notation or change it, or add to it:
CREATE EXTENSION foo WITH SCHEMA utils;
CREATE EXTENSION utils.foo;
I guess if you schema qualify the extension's name we could use that as
the schema name, but remember that the control file name would then be
different from the (qualified and given) extension's name. Surely we
would not try to find the utils.foo.control file, right?
The schema name is also used as a placeholder in the extension SQL
script, so it is somewhat weird to have it in the extension's name.

Are you proposing that an extension object is schema qualified? Would we
lower creating extension privileges to database owners, too, rather than
