How many objects are typically stored to one column?

This approach has nothing to do with relational, nor does it treat objects in an intelligent way.

How does this mechanism

- restore relations between objects in different columns?
- behave on changes to classes?
- perform queries without having to instantiate objects?
- create indices for object members?

I also question the generalization "relational databases" in your statement. Some rare badly designed engines might store objects this way, because they have no other means to solve the object-relational mismatch. I would not recommend using this function.

Kind regards,
