Hash support for row types
Add hash functions for the record type as well as a hash operator
family and operator class for the record type. This enables all the
hash functionality for the record type such as hash-based plans for
UNION/INTERSECT/EXCEPT DISTINCT, recursive queries using UNION
DISTINCT, hash joins, and hash partitioning.
