RelationClearRelation(rebuild == true) calls RelationReloadIndexInfo() for indexes. We can rely on that in RelationIdGetRelation(), instead of calling RelationReloadIndexInfo() directly. That simplifies the code a little. In the passing, add a comment in RelationBuildLocalRelation() explaining why it doesn't call RelationInitIndexAccessInfo(). It's because at index creation, it's called before the pg_index row has been created. That's also the reason that RelationClearRelation() still needs a special case to go through the full-blown rebuild if the index support information in the relcache entry hasn't been populated yet.
