No
when specifying search_path, we build another schema, where each duplicate data must be inside
what I suggested is to have versions/aliases for schemas and any duplicate table/view/... could be inherited if duplicate with all data inside and when any version/alias is dropped and another version/alias has the same table it's preserved, with data inside
that's different behavior where tables attach to schema and if inherited from version/table it may create/reuse it with/without data inside
and this behavior is resource lightweight for migrations
it also could introduce shared tables between schemas
Hope this helps

Isn't this same as adding the required schema name in the search_path?
