It would be hard to reject at the grammar level, and not very friendly
either because you'd only get "syntax error". We could certainly make
the runtime code throw an error if you gave a column list without saying
ANALYZE. But on the other hand, why bother? I do not remember ever
seeing a question that boiled down to somebody being confused by this.
