Can we remove the tests and add them to #638 rather than commenting out?

This is a temporary limitation we have to introduce to make sure
people are not adding generated columns to their existing tables.
Right now, with the current approach if someone adds a new generated
column to their big table, PostgreSQL has to write the new stored
value or generate the new identity for every row, leading to possible downtime.
