you don't get my point I want to do something like this

Other thing that I have noticed that If we remove reference from a field (and it is still in the model mean we don't remove the field but just the references) it reference in database will not be removed as we are only removing constraint from the field which have some references in the code.

To explain what I meant in my previous comment: removing constraints is a destructive operation, and the base sync does not do that. I see that in your initial comment you mentioned using the alter option, which could do this kind of operation

What about if we add name constraint and check if it is not exist with that name and drop if exists
adding name constraint

searching for name constraint
