We can't support these properly, since once the relation's physical files are unlinked, there's no way to roll back the transaction. I suppose we could postpone the unlink till transaction commit, but then what of BEGIN; DROP TABLE foo; CREATE TABLE foo; ? The code does allow dropping a table/index created in the current transaction block, however, since the post-abort state would be that the table doesn't exist anyway.
