EXPLAIN ALTER TABLE would be the next step I guess. I discovered plenty
of magic tricks when working on the rewriting support for that command,
and I think exposing them in the EXPLAIN output would go a long way
towards reducing some POLA violations.
Ideally the EXPLAIN command would include names of new objects created
by the command, such as constraints and indexes.
