So, I'm planning to split the changes into two commits. The first one fixes
for dropped columns, and the second one adds generated columns check/test.
Is that the right approach for such a case?

Still, even the first commit fails to apply cleanly to PG12 (and below).
What is the procedure here? Should I be creating multiple patches per version?
Or does the committer prefer to handle the conflicts? Depending on your reply,
I can work on the followup.
I'm still attaching the dropped column patch for reference.

I tried to reproduce this bug in backbranch.
Generated column is introduced in PG12, and I reproduced generated column problem
in PG12~PG15.
For dropped column problem, I reproduced it in PG10~PG15. (Logical replication
was introduced in PG10)
So I think we should backpatch the fix for generated column to PG12, and
backpatch the fix for dropped column to PG10.
