Related to the other idea of seeing the problems that exist in all the columns (instead of one column at a time), I think it'd be reasonable to have a SRF that spit out everything you'd need to fix to allow inheritance to be added. A schema diff won't know what specifically has to match, but our code does.
Sure, I think that's totally true that I could just make a Set-Returning-Function (that's what SRF stands for right?) that would accomplish this. I'll try that path instead for now.
