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.
