Right ... the problem, as I understand, is that the syntax for
[[maybe_unused]] is different from what we can do with the current
pg_attribute_unused -- [[maybe_unused]] goes before the variable name.
We would need to define pg_attribute_unused macro (maybe have it take
the variable name and initializator value as arguments?), and also
define PG_USED_FOR_ASSERTS_ONLY in the same style.
