Using JSON/JSONB type in postgresql is usually due to the use case that the
keys (top level included) can not be predefined. this is the major
difference between NoSQL/Document and RDBMS.
Why would TOAST have to be used? Can some speciailly structured "raw"
files be used
outside current database files? and jsonb column value would be a pointer
to that file.
