refactor: Pass relation OID instead of Relation to createForeignKeyCheckTriggers()
Currently, createForeignKeyCheckTriggers() takes a Relation type as
its first argument, but it doesn't use that argument directly.
Instead, it fetches the relation OID by calling RelationGetRelid().
Therefore, it would be more consistent with other functions (e.g.,
createForeignKeyCheckTriggers()) to pass the relation OID directly
instead of the whole Relation.
