I understand - and I agree.
small note: Private variables should not be executed from any SQL, because
SQL has not directly related schema. It can be executed only from SQL
embedded in some object with attached schema - PL functions, views,
constraints, .. So for this use case, the important information is info
about a container. We have to hold info about related schema in
