Review Comment:
yeah I realized this as well when reading from RowDataReader, looks like if
there's position delete present it will always add `pos` metadata column as
required in
https://github.com/apache/iceberg/blob/684f7a767c2c216a402b60b73d2d55ef605921a0/data/src/main/java/org/apache/iceberg/data/DeleteFilter.java#L260-L263,
as well as equality delete id if equality delete are present.
