This is a continuation of the work of marclerodrigues in No easy way to find previous state.
One of the concerns was:
This PR adds checks to see if the column exists before querying it, therefore users who have not added this column will be able to continue with existing behaviour. This means that this is not a breaking change.
Persisting this information means that accessing it is faster and easier and avoid problems such as mentioned in this comment and the issue containing it.
