It took me a couple of minutes to get what you meant here.  The point
is that schema-qualifying any of the object specified after the CREATE
SCHEMA with a schema name different than the rolname would cause a
crash, when no schema is directly given.  We should fail with the same
error than when a schema is specified, as of, except that the rolename
needs to be specified:
=# create schema popo authorization postgres create table lala.aa (a int);
ERROR:  42P15: CREATE specifies a schema (lala) different from the one being created (popo)

That seems quite old, at quick glance (v11 fails), so this needs to be
fixed all the way down.  Will fix, nice catch!
