The old fetchall_hashref had its functionality merged into fetchall_arrayref (see the docs), since it didn't actually return a hash reference (and neither does yours), but with the right options, fetchall_arrayref will return an array of hash references as yours does.

There is a new fetchall_hashref, which you give a key field to, and it returns a reference to a hash of hash references.
