The analogy is not with the command -- it is with with the token
'userid'.
The key word prefix tells what that token is supposed to be, and that
is an <authorization-id>.  THe key word AUTHORIZATION works like a sort
of an 'adjective'.

I thought you were arguing that neither would a schema (i.e., you wanted
objects in a schema to have different owners).

Anyway, that is not the point here. We have two commands that
create groups of database objects (our "database" is the SQL catalog)
and both specify who will own it.  The CREATE DATABASE is implementation
defined and we can do whatever we want with it, but as we have a
standard
command that uses a syntax to specify the owner I think we should follow
it.


With the additional advantage that the '=' problem goes away and we
avoid
future shift/reduce problems in the parser as 'WITH' is already too
overloaded.
