Thats quite ok. I think my plan now is to have a table returning function that executes a query dynamically. The query has a where caluse that is first constructed.
Like this:
return query execute format('select d.x, d.y from %1$I.%1$I d where d.period_version = any(' || quote_literal(_periode_version_array) ||'::text[])', register_in);
