RelationCreateStorage(), which creates the main fork, has no such
check. Seems better to stay symmetric, even if it's not strictly
necessary.

I've gone back and forth on this, I can't really convince myself either
way. We might end up reusing init forks for 'global temporary tables' or
somesuch, so being a bit stricter seems slight better. Anyway, it's of
no actual consequence for now.
