Well, we allow a lot of things. Violations of the SQL standard happen
when a command that appears in the standard doesn't do what the standard
says. Allowing commands that are not in the standard is not a violation.
While there is no huge use case for these particular cases, tolerating
redundant options is sometimes useful.
