[GENERAL] How to drop column from interrelated views

I’ve gone to the leaf dependencies and removed the field from them. But I can’t remove the field from the intermediate views because Postgres doesn’t appear to be clever enough to see that the leafs no longer depend on the column. Or did I just miss one?

In general, this seems like a major weakness expressing a model in Postgres (I get that any such weakness derives from SQL; that doesn’t stop me wanting a solution).

Thoughts? Comments?

Thanks in advance.
