Required columns of the default expression should not be converted to NULL, since this map value to default and MATERIALIZED values will not work. Consider the following structure: - A Nullable(Int64) - X Int64 materialized coalesce(A, -1) With recursive_null_as_default=true you will get: _CAST(coalesce(A, -1), 'Int64') AS X, NULL AS A And this will ignore default expression. Fixes: #23524 (Cc: @kssenii) Fixes: #29729 (Cc: @tavplubix) Backport: 21.7+
