fn ensure_no_blocking_dependents(
    scx: &StatementContext<'_>,
    object_type: ObjectType,
    catalog_item: &dyn CatalogItem,
    also_dropped: &BTreeSet<CatalogItemId>,
) -> Result<(), PlanError>
Expand description

Errors if dropping catalog_item would leave a dangling dependent, i.e. an object that depends on it and is not itself being dropped. Dependents whose ids are in also_dropped are ignored, since they are being dropped as part of the same statement.
