Remove the row_security=force GUC value.
Every query of a single ENABLE ROW SECURITY table has two meanings, with the row_security GUC selecting between them. With row_security=force available, every function author would have been advised to either set the GUC locally or test both meanings. Non-compliance would have threatened reliability and, for SECURITY DEFINER functions, security. Authors already face an obligation to account for search_path, and we should not mimic that example. With this change, only BYPASSRLS roles need exercise the aforementioned care. Back-patch to 9.5, where the row_security GUC was introduced. Since this narrows the domain of pg_db_role_setting.setconfig and pg_proc.proconfig, one might bump catversion. A row_security=force setting in one of those columns will elicit a clear message, so don't.
