The information schema is supposed to contain a view SQL_SIZING which is
defined thus:
List the sizing items defined in this standard and, for each of
these, indicate the size supported by the SQL-implementation.
But the standard does not define any "sizing item" or anything like that
anywhere.
Unless someone can offer an explanation, I am inclined to just supply an
empty table and check off this item.
